Cell body reorganization in the spinal cord after elective surgery to treat palmar sweating

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.

Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

In 70 % compensatory sweating severe, recurrence rates were 15% and 19% at 1 and 2 years after surgery

In T2 and T3 resection, all patients experienced Compensatory Sweating and over 70% of the patients felt it was severe. Even in T2 resection, 90% of patients experienced CS and in 50% of these it was severe. High rates of CS are reported in Asian countries with hot and humid climates.

In T2 resection, recurrence rates were 15% and 19% at 1 and 2 years after surgery.It was not rare for a patient to experience recurrence more than 3 years after surgery.

After sympathectomy for hyperhidrosis, very severe discomfort and hyperhidrosis occurred with alarming frequency and intensity

"After thoracoscopic sympathectomy for hyperhidrosis, very severe discomfort and hyperhidrosis in the neighboring non-sympathectomized regions occurred with alarming frequency and intensity."

Conditions arising after Sympathectomy

After stellate ganglion blockade: HORNER'S SYNDROME

  • Drooping eyelid
  • Constricted pupil (impaired vision in low light)
  • Absent/reduced sweating one side of the face and head
  • Redness of eyes
  • Facial flushing

After regional sympathectomy: DUMPING SYNDROME:

  • Rapid emptying of the stomach: lower end of small intestine fills too quickly
  • Early dumping: nausea/vomiting/bloating/diarrhoea/shortness of breath
  • Late dumping: 1-3 hours after eating: weakness/sweating/dizziness
  • Both types may co-exist.

Guillain-Barré syndrome

Paraneoplastic syndromes

Pure autonomic failure (formerly called idiopathic orthostatic hypotension)

Other causes of autonomic dysfunction: sympathectomy

Patients with progressive autonomic dysfunction (including diabetes) have little or no increase in plasma noradrenaline and this correlates with their orthostatic intolerance (Bannister, Sever and Gross, 1977). In patients with pure autonomic failure, basal levels of noradrenaline are lower than in normal subjects (Polinsky, 1988). Similar low values are observed in patients with sympathectomy and in patients with tetraplegia. (p.51)

The finger wrinkling response is abolished by upper thoracic sympathectomy. The test is also abnormal in some patients with diabetic autonomic dysfunction, the Guillan-Barre syndrome and other peripheral sympathetic dysfunction in limbs. (p.46)

Other causes of autonomic dysfunction without neurological signs include medications, acute autonomic failure, endocrine disease, surgical sympathectomy . (p.100)

Anhidrosis is the usual effect of destruction of sympathetic supply to the face. However about 35% of patients with sympathetic devervation of the face, acessory fibres (reaching the face through the trigeminal system) become hyperactive and hyperhidrosis occurs, occasionally causing the interesting phenomenon of alternating hyperhidrosis and Horner's Syndrome (Ottomo and Heimburger, 1980).

Bilateral sympathectomy produced fatal heart block in a few of their experiments

Mendlowitz. Schauer, and Gross4 pointed out that the heart rate became slower after removal of the sympathetic chain, but this bradycardia was only temporary. Bilateral sympathectomy produced fatal heart block in a few of their experiments.

American Heart Journal
Volume 22, Issue 4, October 1941, Pages 545-548

bradycardia and other cardiac complications are common side effects?

The most common side effects of sympathectomy are compensatory sweating, gustatory sweating and cardiac changes including decreasing heart rate, systolic-diastolic and mean arterial pressure. The mechanism of bradycardia and other cardiac complications that develop after thoracic sympathectomy are still unclear.

impairment of autoregulation after unilateral cervical sympathectomy

Although these findings argued against a neurogenic mechanism, James at al. (1969) reported impairment impairment of autoregulation after unilateral cervical sympathectomy in the babbon. Gotoh et al. (1971/1972) observed impairment of autoregulation in patients with the Shy-Drager syndrome.
It was concluded that the autonomic nervous system plays an important role in the mechanism of autoregulation of CBF and that his mechanism is independent of the chemical control of the cerebral vessels. This was confirmed by direct observation of the pial vessels in cats, where separate sites of action in the vascular tree for autoregulation and chemical control were demonstrated; the autoregulatory reaction was located in pial arteries with a diameter larger than 50 μ, and the reaction to carbon dioxide in pial arteries of smaller diameter (Gotoh et al. 1975).
They concluded that the arteries operating in autoregualtin were the larger ones with the dense innervation, while the smaller arteries with sparse innervation were involved in chemical control.
Coronna and Plum (1973) demonstrated the absence of CBF autoregulation in a patient with a Shy-Drager syndrome who had a postganglionic denervation....

Gotoh et al (1979) subsequently showed that autoregulation in patients with this syndrome was impaired irrespective of the localization of the damage to the cervical sympathetic nervous system (preganglionic, central, postganglionic) as judged by the eye instillation test.

Lack of disclosure to ETS patients is unethical and would be criminal in a just society

It is the doctor's moral and ethical duty to provide you with full and honest disclosure of the facts prior to surgery. The whole doctrine of informed consent is to prevent patients from having to realize they made a mistake in hindsight. You shouldn't have had to find out from a former patient's wife that the surgery would cause drenching sweating on your back. It was Garza's job to do that. He completely lied to you regarding the supposed reversibility. Anyone who goes through medical school knows that can't crush a nerve with a metal clamp, remove it later and have the nerve return to normal functioning.

Although it is not possible to predict exactly what will occur in each individual case, there is nearly 100 years of published scientific and medical research available on the effects of sympathectomy. That research paints a very different picture of the effects of this surgery than the one presented to patients considering this surgery. That's the issue. Generally, they lie and tell patients that CS is inconsequential in all but a tiny fraction of cases and simply fail to disclose a huge number of verified adverse effects of the surgery. They take advantage of the patient's ignorance on medical matter. It's unethical and would be criminal in a just society.

In short, you do have a way of knowing what will likely occur as a result of the surgery before you have it done. All the information necessary to make an informed decision exists. It's just not getting to patients.
