The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer: "Immediately after sympathectomy, the contralateral right arm became increasingly cold and cyanotic and the patient complained of chronic painful coldness and severe cold-intolerance in the right arm. Attempts to pharmacologically vasodilate the arm with felodipine did not affect the local vasoconstriction and pain. Dorsal column stimulation (associated with symmetrical paraesthesia in both arms) induced an immediate and marked (ten-fold) increase in skin blood flow in the right arm (and in the leg), whereas skin blood flow in the left arm remained unaffected. The lack of vasomotor response in the left arm was not due to maximal vasodilatation at rest, since skin blood flow in the left arm showed a normal capacity for axon reflex vasodilatation following antidromic activation of sensory afferents. The results suggest that the marked vasodilatation induced by dorsal column stimulation is mediated by sympathetic vasomotor fibres, via modulation of central neuronal circuits involved in the regulation of skin sympathetic discharge."

catecholamine released from sympathetic nerves, acquires the capacity to activate pain pathways after tissue or nerve injury

What Is Reflex Sympathetic Dystrophy Syndrome or RSD?: "According to the National Institute of Neurological Disorders and Stroke (NINDS), RSD is "a chronic pain condition that is believed to be the result of dysfunction in the central or peripheral nervous systems." According to MedicineNet, RSD involves "irritation and abnormal excitation of nervous tissue, leading to abnormal impulses along nerves that affect blood vessels and skin."

Animal studies indicate that norepinephrine, a catecholamine released from sympathetic nerves, acquires the capacity to activate pain pathways after tissue or nerve injury, resulting in RSD. Another theory suggests that RSD, which follows an injury, is caused by triggering an immune response and symptoms associated with inflammation"

Transection below T8-T10 is not accompanied by reflex sweating

Reflex sweating in patients with spina... [Arch Phys Med Rehabil. 1977] - PubMed - NCBI: "Sweat glands derive their innervation from the sympathetic nervous system. The spinal sympathetic structures that are located in the intermediolateral areas extend from T1-L2 segments and are under the control of hypothalamic centers. Cord transection abolishes the supraspinal control of sudorimotor function. Since sympathetic innervation does not follow a clear segmental distribution, normal sweating may be preserved at a higher or lower level than skin sensation. Nonthermoregulatory reflex sweating is an indication of unchecked spinal cord facilitation and is precipitated by afferent stimuli from bladder, rectum, and various other sources. It is usually a manifestation of mass reflex or autonomic crisis and occurs particularly in cervical or high thoracic lesions. Transection below T8-T10 is not accompanied by reflex sweating. The phenomenon of thermal relfex sweating is controversial. Although some aspects of nonthermoregulatory reflex sweating are still unclear, proper immediate and continuing preventive management will reduce the incidence of this and other autonomic manifestations.

Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for hyperhidrosis

T3 sympathicotomy segment was the most frequent transection done (95.83%), as only ablation (25%) or in association with T4 (62.50%) or with T2 (8.33%). It was observed increase in RI and PI of the common carotid artery (p < 0.05). The DPV of internal carotid artery decreased in both sides (p < 0.05). The SPV and the DPV of the right and left vertebral arteries also increased (p < 0.05). Asymmetric findings were observed so that, arteries of the right side were the most frequently affected.
CONCLUSIONS: Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for PH. SPV was the most often altered parameter, mostly in the right side arteries, meaning significant asymmetric changes in carotid and vertebral vessels. Therefore, the research findings deserve further investigations to observe if they have clinical inferences.

Sympathectomy vs sympathotomy

Sympathectomy vs sympathotomy. Sympathectomy, with use of ganglionectomy and by definition, must sever the primary axon from the neuron in the intermediolateral cell column of the spinal cord (red) before primary or collateral synapse in the T2 ganglion. This injures all the neurons at this level of the spinal cord, some of which may die, and may predispose the patient to spinal cord reorganization and severe compensatory hyperhidrosis. Sympathotomy interrupts only axons after potential T2 ganglion synapses, a less injurious effect on the neuron, and is the least destructive procedure possible with successful treatment of palmar hyperhidrosis.

Gustatory sweating, flushing and other responses after sympathectomy

Gustatory sweating on the head, neck and arms, often occurs after cervico-thoracic sympathectomy. Haxton (1948) reported an incidence of 36 percent, the same as in the present series. It was thought that some information about regeneration in the cervical sympathetic might be revealed by investigation of this surgical curiosity.

Although sweating is the common gustatory response after cervical sympathectomy, other changes are experienced. Haxton (1948) described associated paresthesia and flushing, gooseflesh may occur (Herxheimer, 1958) and vaso-constriction is reported in this paper. These occur together or separately and occasionally sweating might be absent. The subject has been confused by comparison with post-parotidectomy gustatory sweating which has a different mechanism (Glaister et al.,1958; Bloor, 1958).

Sweating is produced by cholinergic sympathetic fibres. In normal individuals both vasocontriction and gooseflesh are adrenergic. This also holds in gustatory responses.  Figure 2 shows blocking of sweating by atropine, whilst gooseflesh continues unchanged.
   The tingling sensations were described as being unlike normal sensation, and likened to plucking out of hair. In one patient in was so unpleasant that she refused to take a test stimulus. Flushing usually occurs on the upper chest and neck, and is an erythema with sharp demarcation, not associated with a rise in skin temperature.
   Of the patients, 29 were found to have gustatory responses, and 24 were studied in detail. Of 22 patients with sweating who could be studied, 11 had gooseflesh, 10 tingling, 6 flushing, and 4 vasoconstriction. Four patients, however, had no sweating and their gustator responses consisted of gooseflesh and tingling in one, tingling alone, and flushing in two. None of these four showed vasoconstriction.
   The stimulus for testing used was usually Worcester sauce, but specificity of the response was sometimes great, and one patient reacted only to boiled sweets made by one particular firm.

Stellate ganglion block may relieve hot flashes by interrupting the sympathetic nervous system

Stellate ganglion block may relieve hot flash... [Med Hypotheses. 2007] - PubMed - NCBI: " the wide range of conditions that have been reported to respond favorably to stellate ganglion block suggest that its effectiveness may not be solely the result of increased blood flow nor restricted just to its sphere of innervation. We have found that stellate ganglion block is effective in the treatment of hot flashes in postmenopausal women, as well as those with estrogen depletion resulting from breast cancer treatment. Based on evidence that hot flashes may be centrally mediated and that the stellate ganglion has links with the central nervous system nuclei that modulate body temperature, we hypothesize that the stellate ganglion block provides relief of hot flashes by interrupting the central nervous system connections with the sympathetic nervous system, allowing the body's temperature-regulating mechanisms to reset. If this mechanism can be confirmed, this would provide women with intractable hot flashes with an effective, potentially long-lasting means of relieving their symptoms, and potentially widen the range of indications for stellate ganglion block to include other centrally mediated syndromes."

patients with palmar hyperhidrosis have no overactivity of the sympathetic nerve

HR and BP at rest and cardiovascular response to exercise were similar in patients with palmar hyperhidrosis before ETS and in the normal control population. Therefore, we consider that patients with palmar hyperhidrosis have no overactivity of the sympathetic nerve. However, because bilateral ETS causes the suppression of cardiovascular response to exercise, patients that has been treated with ETS need to be observed during high-level exercise.

Post-sympathectomy pain

Postsympathectomy limb pain, postsympathectomy parotid pain, and Raeder's paratrigeminal syndrome are pain states associated with the loss of sympathetic fibres and in particular with postganglionic sympathetic lesions. There is a characteristic interval of about 10 days between surgical sympathectomy and onset of pain. It is proposed that this pain in man is correlated with the delayed rise in sensory neuropeptides seen in rodents after sympathectomy. These chemical changes probably reflect the sprouting of sensory fibres and may result from the greater availability of nerve growth factor after sympathectomy. The balance between the sensory and sympathetic innervations of a peripheral organ may be determined by competition for a limited supply of nerve growth factor.

reduction in all proline-richproteins (PRP) in the saliva following sympathectomy

The protein constituents in parasympathetically evoked saliva from normal and short-term sympathectomized parotid gland swere compared. There was a reduction in all proline-richproteins (PRP) in the saliva following sympathectomy. The decrease was quantified for acidic PRP by high- performance ion-exchange chromatography, which showed an increase in the ratio of amylase to other proteins. These results suggest that sympathetic impulses influence the synthesis of PRP and amylase in opposite directions.

Another case of disabled thermoregulation and heatstroke following sympathectomy

We describe an extreme case of compensatory truncal hyper- hidrosis and anhidrosis over the head and neck region which led to a heatstroke. 

Six months after the initial operation, he had an episode of heatstroke while perform- ing outdoor duties which required running for around 5 km. The temperature on the day was between 30–32°C, and the relative humidity was between 75 and 85%. At that time, he complained of light-headedness, ‘feeling’ that heat could not dissipate from his head and neck region and muscle cramp in his legs. He was transferred to a hospital and was found to have a body tem- perature of 40°C and shock. His presentation was similar to a previous report by Sihoe et al. [1] on a patient with post- sympathectomy heatstroke. He was subsequently successfully treated with fluid and electrolyte resuscitation and supportive care.

69% of patients continued to have relief after ETS, patient satisfaction rate was 56%

There were no operative mortalities, minor complications occurred in 22%. Initial success rate was 88%. Median follow up was 93 (24-168) months, response rate to the questionnaire was 85%. Sixty-nine per cent of patients continued to have relief of initial symptoms, whereas patient satisfaction rate was 56%. CS was present in 42 patients (68%). Long-term satisfaction rates per initial indication group were 42% for facial blushing and 65% for hyperhidrosis (n.s.), and CS was present in 79% vs 61%, respectively.

CONCLUSION:

ETS appears a safe treatment for upper limb hyperhydrosis with acceptable long-term results. For excessive blushing, however, long-term satifaction rates of ETS are severely hampered by a high incidence of disturbing compensatory sweating. ETS should only be indicated in patients with unbearable symptoms refractory to non-surgical treatment. The patient information must include the long-term substantial risk for sever CS and regret of the procedure.

"sympathectomy highlighted the disparity between what is known in practice and what appears in the literature"

The March 2004 edition was quite outstanding, with an excellent editorial reminding the reader that only good results are published. The review on thoracoscopic sympathectomy highlighted the disparity between what is known in practice and what appears in the literature. 

‘Know Your Results’, the topic of the ASGBI Annual Scientific Meeting, is of outstanding importance; what is more, the surgeon has to go on knowing his/her results to ensure standards of practice do not slip.

The Journal appreciates comments and criticism and the correspondence column remains a crucial part of the BJS in its interaction between editors and reader. It is also part of the scientific process.

A more robust and incisive criticism of articles known to be flawed would prevent the retractions that have recently been published in the Lancet.

The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy

The effect of bilateral sympathectomy was significantly greater than that of unilateral sympathectomy. Unilateral and bilateral sympathectomy produced similar reductions in the concentrations of NPY-ir and NA in the ventricular tissue. In contrast dissimilar changes were produced in the atrium. Although bilateral sympathectomy almost totally depleted the NA from the right atrium (by 98%), the NPY-ir levels were only reduced by 50%. These results indicate that approximately half the content of NPY in the right atrium is not present in sympathetic noradrenergic neurones.

sympathectomy induced morphological alterations in the masseter muscles

Sympathectomized animals showed varying degrees of metabolic and morphological alterations, especially 18 months after sympathectomy. The first five groups showed a higher frequency of type I fibres, whilst the oldest group showed a higher frequency of type IIb fibres. In the oldest group, a significant variation in fibre diameter was observed. Many fibres showed small diameter, atrophy, hypertrophy, splitting, and necrosis. Areas with fibrosis were observed. Thus cervical sympathectomy induced morphological alterations in the masseter muscles. These alterations were, in part, similar to both denervation and myopathy. These findings indicate that sympathetic innervation contributes to the maintenance of the morphological and metabolic features of masseter muscle fibres.

SURGICAL SYMPATHECTOMY ON THE SENSITIVITY TO EPINEPHRINE OF THE BLOOD VESSELS OF MUSCULAR SEGMENTS OF THE LIMBS

Pursuing this study of the effect of epinephrine on muscle blood flow, Duff and Swan (10) reported that during intravenous epinephrine infusions the initial marked dilatation was succeeded by a second phase of moderate dilatation in normal but not in sympathectomized limbs. Because of its absence in chronically sympathectomized limbs this secondary vasodilatation was at that time thought to be an indirect vasomotor effect mediated by the sympathetic nerves. Re-examination of their data in the light of some subsequent critical experiments now reveals that the difference which they found between normal and sympathectomized limbs may be ascribed largely to vascular hypersensitivity in the later.

In the present paper these additional data are reported, and are incorporated with those of Duff and Swan(10); the whole material being interpreted to provide evidence that hypersensitivity of the vessels of skeletal muscle in the upper and lower limbs may result from pre- and postganglionic sympathectomy in man.

In neurally intact rats which were infected with a known carcinogen, only 1 out of 30 developed a tumor. When sympathectomized (intentional sympathetic nerve interference) rats were injected with the same carcinogen, 24 out of 38 developed tumors. These results confirm that sympathetic block enhances tumor implantation."

Management of reflex sweating in spinal cord injured patients

Reflex sweating can be a problem for cervical spinal cord injured patients. Patient comfort and skin breakdown have been the major concerns. Five patients were studied prospectively, using a patch containing 1.5mg of scopolamine. Patches were changed every third day. Each patient was carefully monitored before and after application of the patch for signs and symptoms of anticholinergic side effects such as dizziness, blurred vision and dry mouth. Patients were also monitored for changes in patch signs before and after use, including residual urine volumes, blood pressure, heart rate, and mental status. Our study indicates that topical scopolamine successfully controlled reflex sweating in 5 patients without anticholinergic side effects.

surgical and chemical sympathectomy can both modulate bone cell function

It is known that surgical and chemical sympathectomy can both modulate bone cell function.  However, the sympathetic
nervous system (SNS) can give rise to both anabolic and catabolic effects [28-31] and its role in regulating bone remodeling is, therefore, controversial. For example, some researches reported that if bone is deprived of its sympathetic innervation, bone
deposition and mineralization is reduced and bone resorption increases [31], while in some other reports a sympathectomy impairs bone resorption [28].

Pain in the form of intercostal neuralgia with dysesthesia at the site of trocar insertion is rarely documented but more frequent than generally recognized

Pain in the form of intercostal neuralgia with dysesthesia at the site of trocar insertion is rarely documented but more frequent than generally recognized. Many centres perform short-stay surgery that may lead to underestimation of pain results. In most series pain resolves within months, but Walles and colleagues could detect a persistence for years (Walles et al., 2008).

left thoracic sympathectomy to prevent electrical storms in CPVT patients

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), a life threatening arrhythmia induced by sympathetic stimulation in susceptible individuals is often refractory to antiarrhythmic agents. First line of treatment, beta-blockers can be ineffective in up to 50% with implantable cardioverter-defibrillator (ICD) placement for refractory cases. Paradoxically ICD can be arryhthmogenic from shock-associated sympathetic stimulation, initiating more shocks and "electrical storms". This has led to the use of more effective beta blockade offered by left sympathectomy, now performed by minimally invasive video assisted thoracoscopic surgery (VATS).
To our knowledge this is first such reported case.

Sympathectomy for the treatment of polymorphic ventricular tachycardia

Bilateral thoracoscopic cervical sympathectomy for the treatment of recurrent polymorphic ventricular tachycardia.

Turley AJ, Thambyrajah J, Harcombe AA.
Despite potassium and magnesium supplements, beta blockade, implantation of a single then dual chamber implantable cardioverter defibrillator (ICD), amiodarone, nicorandil, and mexiletine, the patient continued to experience arrhythmia storms, receiving more than 700 ICD discharges over seven months. She was ultimately treated successfully with bilateral thoracoscopic cervicothoracic sympathectomies. This is the first reported bilateral thoracoscopic treatment of a patient with LQTS and symptomatic life threatening ventricular tachyarrhythmias refractory to current pharmacological and pacing techniques.

The Dangers of ETS Surgery for Excessive Sweating

If you have an excessive sweating problem, you may have heard of endoscopic sympathectomy (ETS) surgery. If you are considering this option - Don't!
This surgery can have severe complications and, in spite of the promises, could leave you in a worse situation than you currently face. Some people have experienced more sweating after the operation than before.
That's right - more sweating. Doesn't sound like a good solution to the problem of excessive sweating, does it? Okay, you have problems with excessive sweating, which can be embarrassing and uncomfortable. You want a solution. That's fair enough. However, ETS Surgery is NOT the solution.

dynamic cerebral autoregulation is altered by ganglion blockade

We measured arterial pressure and cerebral blood flow (CBF) velocity in 12 healthy subjects (aged 29+/-6 years) before and after ganglion blockade with trimethaphan. CBF velocity was measured in the middle cerebral artery using transcranial Doppler. The magnitude of spontaneous changes in mean blood pressure and CBF velocity were quantified by spectral analysis. The transfer function gain, phase, and coherence between these variables were estimated to quantify dynamic cerebral autoregulation. After ganglion blockade, systolic and pulse pressure decreased significantly by 13% and 26%, respectively. CBF velocity decreased by 6% (P <0.05). In the very low frequency range (0.02 to 0.07 Hz), mean blood pressure variability decreased significantly (by 82%), while CBF velocity variability persisted. Thus, transfer function gain increased by 81%. In addition, the phase lead of CBF velocity to arterial pressure diminished. These changes in transfer function gain and phase persisted despite restoration of arterial pressure by infusion of phenylephrine and normalization of mean blood pressure variability by oscillatory lower body negative pressure.
Conclusions-: These data suggest that dynamic cerebral autoregulation is altered by ganglion blockade. We speculate that autonomic neural control of the cerebral circulation is tonically active and likely plays a significant role in the regulation of beat-to-beat CBF in humans.

Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, hypoesthesia, incomplete results, paresthesia in the anterolateral abdominal wall, dyspareunia

The complications and side effects are very significant, such as irreversible compensatory sweating (20% to 50%), low satisfaction with results, Claude-Bernard-Horner syndrome, pneumothorax, hemothorax, asymmetry of results, intercostal neuralgia, causalgia, incomplete results, and anesthetic complications^11-13.

Retroperitoneoscopic lumbar sympathectomy (video-assisted): this technique is effective in the treatment of isolated or persistent plantar hyperhidrosis (compensatory after thoracic sympathectomy). The treatment consists of removing the nerves of the sympathetic chain located in the abdomen, in the anterolateral portion of the lumbar vertebrae. It requires hospitalization and is carried out under general anesthesia. It may lead to complications such as lesions of structures adjacent to the sympathetic chain, light abdominal distension, neuralgia, and causalgia as well as hypoesthesia in the thighs and groin, limitation of leg movement,
paresthesia in the anterolateral abdominal wall, change in libido, dyspareunia, pulmonary thromboembolism, hemorrhages, arrhythmias, and cardiac decompensation, amongst others. It definitively eliminates plantar hyperhidrosis14,15.

Procedural Intervention Guideline 

Vasodilation; Vasomotor Disturbances

Complex regional pain syndromes (CRPS) are characterized by vascular disturbances primary affecting the microcirculation in the distal part of the involved extremity. In the acute stage inhibited sympathetic vasoconstriction and exaggerated neurogenic inflammation driven by central and peripheral mechanisms, respectively, seem to be the major pathophysiological mechanisms inducing vasodilation. During the chronic course of the disease as well as early in some patients vasoconstriction dominates the clinical picture induced by changes in the microcirculation itself such as endothelial dysfunction or vascular hyperreactivity, whereas sympathetic vasoconstrictor activity returns and neurogenic inflammation is less severe. It can be suggested that the interaction between different mechanisms underlying vasomotor disturbances as well as the severity of each single mechanism in the individual patient have a great impact on the variety of the overall clinical picture in CRPS. Irrespective of the underlying pathophysiology, measurements of skin temperature differences between the affected and the contralateral extremity can serve as a diagnostic tool in CRPS, in particular when sensitivity and specificity is increased by considering dynamic alterations in skin temperature asymmetries.

Epidemiology /Etiology

CRPS is found to result:^[1]
- After traumatic injury (65%)

• 1-2% of all fractures result in CRPS
• Largest risk of CRPS for fractures of the wrist

- After surgical intervention (19%)
- Infection (4%)
- Prior inflammation (2%)
- No clear cause (10%)
A review stated that women are predominantly affected, by a factor of 3,5 and a genetic predisposition has also been theorized.
The disease affects all ages, though most cases are between 50 and 70 years old, and it is generally believed to occur mainly in caucasian and Japanese people.^[4]

Characteristics/Clinical Presentation

The following symptoms have been found in literature:^[5]
- Autonomic and trophic disorders:

• Distal Edema in 80% of the patients
• Skin temperature changes at the affected body part in 80% of the patients, initially warmer and in 40% of patients gradually cools down until colder in comparison to the rest of the body as the disease progresses. Another review mentioned that 30% of the patients start off from the primarily cold stage.3
• In 40% of the patients skin at the affected body part starts showing redness, but becomes pale or livid in later stages
• In 55% altered sweating takes place, with hyperhydrosis being more common than hypohydrosis.
• Hair and nail growth possibly increase in early stages
• Atrophy of skin and muscles in later stages, as well as contractures may severely restrict movement

- Sensory disturbances (90%) typically in a glove or stocking-like distribution

• Spontaneous pain occurs in 75%, usually burning dragging or stinging

• 68% felt in deep structures
• 32% felt in skin
• In 77% pain shows fluctuating intensity, lesser proportion shows shooting pain
• Pain can be increased by orthostasis, anxiety, exercise or temperature changes.
• In many cases, pain is more pronounced at night

• Sensory gain (Mechanical hyperalgesia, allodynia, ...) or sensory loss (hypaesthesia, hypalgesia, …) may be present.

- Motor dysfunction

• Motor weakness
• Severe impairment of complex movements
• Impairment of range of motion, initially by concomitant edema, later by contractures and fibroses
• Neglect like symptoms have been found in some patiënts, described as the body part in question feeling foreign.
• Enhanced physiological tremor in around 50%
• Myoclonus or dystonia, especially in type II CRPS

effect of bilateral cervical sympathetic ganglionectomy on the architecture of pial arteries

The influence of the cranial sympathetic nerves on the architecture of pial arteries in normo- and hypertension was examined. For this purpose the effect of bilateral superior cervical ganglionectomy was evaluated in normotensive rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP). The operations were performed at the age of 1 wk, which is just prior to the onset of ganglionic transmission. The length of the inner media contour was measured and the media cross-sectional area was determined planimetrically, with computerized digitalization of projected photographic images of transversely sectioned pial arteries. Four wk after sympathectomy there was a 20% reduction in media cross-sectional area and a consequent reduction in the ratio between media area and calculated luminal radius in the major pial arteries at the base of the brain in WKY but not in SHRSP. Conversely, in small pial arteries linear regression analysis showed that in WKY subjected to ganglionectomy the relationship between media cross-sectional area and luminal radius was significantly larger in arteries with a radius less than 21 microns compared to untreated WKY. No such effect was seen in the corresponding SHRSP vessels. In addition, the cross-sectional area of the internal elastic membrane (IEM) in the basilar arteries of WKY was measured by means of a computerized image-analysing system. Mean cross-sectional area of the IEM was approximately 45% larger following SE than in control animals. The present findings propose a 'trophic' role for the sympathetic perivascular nerves in large pial arteries of the rat. The increased media-radius ratio in the small pial arteries of the WKY following sympathectomy might reflect a compensatory hypertrophy due to reduced protection from the larger arteries against the pressure load. The inability to detect any morphometrically measurable effect of the sympathectomy in the cerebral arteries of SHRSP is probably explained by a marked growth-stimulating effect of the high pressure load in these animals.

Postural Hypotension and Postural Dizziness

The subjects were 204 consecutive non–insulin-dependent patients with diabetes and 408 age- and sex-matched nondiabetic control subjects who underwent physical examinations for preventive reasons at the National Cheng Kung University Hospital between October 1992 and September 1994. Subjects were excluded from the study for sympathectomy, anemia, thyroid disorder, pregnancy, chronic alcohol use, and/or use of anti-Parkinson drugs, narcotics, sedatives, antipsychotic agents, or antidepressants within 2 weeks of the study. The subjects with diabetes included 114 men and 90 women with a mean age ± SD of 57.9 ± 10.5 years. The nondiabetic control subjects were 228 men and 180 women with a mean age ± SD of 57.1 ± 9.5 years.

sympathectomy affects the heart, sweating, and circulation

heart rate was significantly reduced at rest (14%), at sub-maximal exercise (12.3%), and at peak exercise (5.7%), together with a significant increase in oxygen pulse (11.8, 12.7, and 7.8%, respectively). The rate pressure product (RPP) was also significantly reduced following the surgical procedure at all three study stages, while all other physiological variables measured remained unchanged. It is suggested that thoracic-sympathetic denervation affects the heart, sweating, and circulation of the respective denervated region

Post-sympathectomy neuralgia is a severe complication since pain can be permanent, severe, and incapacitating

http://www.springerlink.com/content/q04711t06j164206/

"ETS has proved moderately successful in treating hyperhidrosis, although the operation does carry a high risk of complications. "

Other complications of ETS include:

• sweating on the face and neck after eating food (gustatory sweating),
• inflammation of the nose (rhinitis), and
• air becoming trapped between the layers of the lung (pneumothorax) which can cause chest pain and breathing difficulties (although this usually resolves itself without the need for treatment).

Rarer complications of ETS include:

• Horner's syndrome, a condition that causes drooping of the eyelids, and
• damage to the phrenic nerve (a nerve that is used to help in breathing).

Phrenic nerve damage can lead to shortness of breath, though it may be possible to repair the nerve during surgery.

ETS has proved moderately successful in treating hyperhidrosis, although the operation does carry a high risk of complications.

Ovarian sympathectomy as treatment for pain

Lateral pelvic structures receive their innervation mostly via nerve fibres traversing the infundibulopelvic ligaments. Thus, for lateral pelvic pain, ovarian sympathectomy could theoretically alleviate the pain. However it is rarely performed because of the high risk of vascular complication and its squeal on ovarian functions.

sympathectomy improves skin blood flow at the thermoregulatory but not the nutritive level of skin microcirculation

sympathectomy improves skin blood flow at the thermoregulatory but not the nutritive level of skin microcirculation. This may be related to the fact that the thermoregulatory vessels are mainly sympathetically controlled, whereas the nutritive capillaries are mainly controlled by local (nonneural) factors.

Variations in dynamic lung compliance during endoscopic thoracic sympathectomy with CO2 insufflation

The current study examined the effects of capnothorax on dynamic lung compliance (DLC) of the ventilated lung during ETS.
One way analysis of variance (ANOVA) was used for analysis of data before, during and after OLCV. P<0.05 was considered significant. The mean values of the DLC were 52 +/- 6, 30 +/- 3, 39 +/- 5 and 53 +/- 9 ml/cmH(2)O before, during (at 10 and 5 mmHg IPP) and after OLCV respectively with significant differences before and at 10 and 5mmHg IPP. In conclusions, during OLCV and capnothorax for ETS, DLC tends to decrease with increasing of intrapleural CO(2) insufflation pressure. However, in short procedures it has no deleterious postoperative effect. To the best of our knowledge this is the first study performed to investigate DLC changes during OLCV with capnothorax.

Iatrogenic harlequin syndrome resulting from sympathectomy

Postgrad Med J 2003;79:278 doi:10.1136/pmj.79.931.278

A 29 year old man with severe facial hyperhidrosis underwent an uncomplicated right thoracoscopic sympathectomy. Before operating on his left side, a starch-iodine preparation was applied to his face in order to demarcate residual sudomotor function. The preparation becomes blue on exposure to moisture, thereby representing residual sweat gland activity.

Figure 1 demonstrates that sympathetic innervation to the face is strictly unilateral, and nerve fibres do not appear to cross the midline. This is essentially an iatrogenic variation of the harlequin syndrome,² which usually results from interruption of post-ganglionic sympathetic fibres secondary to malignant invasion.

His facial hyperhidrosis was completely treated once the contralateral sympathectomy was performed.

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis

We found statistically significant differences (P < 0.001) between the preoperative P/I ratio [0.40 mm (standard deviation, SD 0.07 mm)] and the postoperative basal ratio [0.33 (SD 0.05)] at 24 h. The P/I ratio at 24 h increased from 0.33 to 0.36 (SD 0.09), a nonsignificant increase (P = 0.45), after instillation of medicated eye drops. No differences were observed between the preoperative [0.40 (SD 0.07)] and 1-month basal values [0.38 (SD 0.07)], and instillation of apraclonidine no longer induced a hypersensitivity response.

CONCLUSIONS:

T3 sympathectomy leads to subclinical pupillary dysfunction with a tendency for miosis, even though this impairment is not generally evident on standard physical examination or reported by patients. This subclinical dysfunction may be caused by injury to an undefined group of presympathetic nerve cell axons in caudocranial direction that communicate with the cervical sympathetic ganglia and whose function is mydriatic pupillary innervation.

The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space

Presence of the stellate ganglion was noted in 56 (84.8%) sides, and 6 (9.1%) sides showed a single large ganglion formed by the stellate and the second thoracic sympathetic ganglia. The second thoracic sympathetic ganglion was most commonly located (50%) in the second intercostal space. CONCLUSION: The anatomic variations of the intrathoracic nerve of Kuntz and the second thoracic

sympathetic ganglion were characterized in human cadavers.

Sympathectomy increased the pain threshold and made the sympathectomized rats hypesthetic

Normal adult rats were sympathectomized at L2-L3. The threshold for thermal noxious pain by hot-plate analgesia test and changes in neuropeptides in the lumbar dura mater and dorsal root ganglia using light microscopic immunohistochemistry were assessed and compared with control rats.

Results: In the hot-plate analgesia test, sympathectomized rats increased their hot-plate latency time compared with that of sham-operated rats. Density of calcitonin gene-related peptide immunoreactive fibers in sympathectomy side of the lumbar dura mater decreased to 45.5% compared with the contralateral side. The number and size of calcitonin gene-related peptide immunoreactive cells in dorsal root ganglia showed no difference between sympathectomized and contralateral side.

Conclusion: Sympathectomy increased the pain threshold and made the sympathectomized rats hypesthetic. A large numbers of sensory fibers innervated the lumbar dura mater via L2-L3 sympathetic nerve in rats. Sympathectomy reduced the number of these nerve fibers in the lumbar dura mater. Sympathetic nerves may play an important role for low back pain involving the lumbar dura mater.

Long-term sympathectomy induces sensory and parasympathetic fibres sprouting, and mast cell activation in the rat dura mater

http://discovery.ucl.ac.uk/1330488/

There are similarities between the delayed onset of the human pain state and the delayed rise in sensory peptides after sympathectomy

The effect of sympathectomy on the calcitonin gene-related peptide (CGRP) level in the rat primary trigeminal sensory neurone was investigated. Six weeks after bilateral removal of the superior cervical ganglion there was a 70% rise in the CGRP content of the iris and the pial arteries, a 34% rise in the concentration in the trigeminal ganglion but no change in the brainstem. The CGRP rise in both end organs suggests that this phenomenon may be common to all peripheral organs receiving combined sensory and sympathetic innervations. The lack of any rise in the brainstem CGRP content raises the possibility that this process spares central terminations. In contrast, the level of neuropeptide Y, a peptide mainly contained in sympathetic terminals, fell to 35% of control values in the iris and pial arteries whilst the trigeminal ganglion and brainstem concentrations remained unchanged. The possible relevance of these observations to the clinical syndrome of postsympathectomy pain (sympathalgia) is discussed. There are similarities between the delayed onset of the human pain state and the delayed rise in sensory peptides after sympathectomy.

Digital infrared thermal image after T2 sympathicotomy or T3 ramicotomy

(A) Clear cut change of skin temperature after a T2 sympathicotomy. (B) An even distribution of skin temperature after ramicotomy.

Gossot and colleagues [8] analyzed a group of T2, T3, T4 sympathectomy patients in comparison with a group of patients undergoing a T2, T3, T4 ramicotomy and they reported no statistical difference regarding the incidence of CS between the two groups studied (72.2% and 70.9%). However in terms of the severity of CS (embarrassing, disabling) causing inconveniences to daily life, they reported 27% and 13% incidences in these two groups, respectively. These findings suggest that by preserving the sympathetic trunk, it was possible to reduce the severity of CS.

The preganglionic fibers of the sympathetic nerve to the arm originate mostly from the spinal segments T3–T6 and the postganglionic fibers of the sympathetic nerve to the arm originate from T2 and, to a lesser extent, the T3 ganglia [9]. This implies that the division of preganglionic fibers (rami communicantes) reduces the extent of denervation of the sympathetic nerve as compared with the division of postganglionic fibers (sympathetic trunk) in the treatment of palmar hyperhidrosis.
Sympathectomy or sympathicotomy is one of the procedures used to divide the sympathetic trunk. Sympathicotomy distinctively changes sympathetic nerve distribution in comparison with a ramicotomy. Figure 4A illustrates the clear-cut changes of skin temperature after a T2 sympathicotomy. However the overall sympathetic nerve distribution to the body is not markedly changed after a T3 ramicotomy because a T3 ramicotomy is a procedure that is used to divide one of the preganglionic fibers and to preserve the sympathetic trunk. Figure 4B illustrates an even distribution of skin temperature after T3 ramicotomy.
