results of sympathectomy deteriorate with time

results of sympathectomy deteriorate with time (T.S. Lin & Fang, 1999; Walles et al., 2008). This recurrent postoperative sweating may be due to local nerve regeneration but has not yet been proven (Lee et al., 1999).

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.

compensatory sweating is extremely common and often worse than the original problem

Endoscopic thoracic sympathectomy is useful only when all other treatments fail and then should be considered only with caution as compensatory sweating is extremely common and often worse than the original problem.

cutaneous area innervated by the sympathetic T2 and T3 ganglia extends to zones influenced by T1 in up to 20.75% of patients

The territory influenced by the T2 and T3 sympathetic ganglia is more extensive than has been described by classical anatomical studies. The cutaneous area innervated by the sympathetic T2 and T3 ganglia extends to zones influenced by T1 in up to 20.75% of patients with primary hyperhidrosis.

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.

limited understanding of the role of the sympathetic nervous system in mediating pain

The role of sympathetic blocks in herpes zoster (HZ) and postherpetic neuralgia (PHN) remains controversial due to methodologic shortcomings in published studies and limited understanding of the role of the sympathetic nervous system in
mediating pain.

Local anaesthetic block of the sympathetic chain can be used to produce transient increase in blood flow to a limb (stellate ganglion block for arm, lumbar sympathetic block for leg).
Neurolytic (phenol) lumbar sympathectomy can increase lower limb blood flow for up to 6 months. Neurolytic stellate ganglion block carries high risk of injury to adjacent nerves and is rarely used. 

SCS can improve tissue perfusion in ischaemic heart disease and peripheral vascular disease.

What is the evidence?
Neurolytic lumbar sympathectomy increases popliteal artery flow and perfusion of leg muscles in peripheral vascular disease42. A prospective series has shown total relief of pain and healing of ulcers in 58.7% of cases of non-operable peripheral vascular disease43. 

Both retrospective44 and prospective45 case series support a role for SCS in the management of refractory angina pectoris. Use of SCS resulted in reduced anginal symptoms and medication use.

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.
