"Sympathectomy is a technique about which we have limited knowledge, applied to disorders about which we have little understanding."

The custom of a majority is no guarantee of safety and is seldom a guide to best medical practice.


Cameron`s claim that there has been only one death attributable to synchronous bilateral thoracoscopic sympathectomy is implausible. Surgeons and anaesthetists are reticent in publicizing such events and Civil Law Reports of settled cases are an inadequate measure of the current running total. The custom of a majority is no guarantee of safety and is seldom a guide to best medical practice.

a post-sympathectomy denervation of the lower regions of the body, associated with incapacitating postural hypotension


The traditional biochemical tests of sympathetic nervous system function used in clinical diagnosis (urine and plasma catecholamine measurements) are indices of "overall" sympathetic nervous activity, and incapable of detecting localised changes in sympathetic tone confined to individual organs. Recently developed radiotracer methods, which enable the pattern of sympathetic nervous dysfunction in disease states to be delineated, were used to detect abnormalities in regional sympathetic nervous system activity in two patients presenting problems in management. In one, the abnormality of sympathetic function was iatrogenic, a post-sympathectomy denervation of the lower regions of the body, associated with incapacitating postural hypotension. In the other, unexplained persistent sinus tachycardia proved to be due to an increase in sympathetic nervous tone restricted to the innervation of the heart. Knowledge of the underlying sympathetic nervous pathophysiology in these patients influenced the choice of drugs subsequently used in their treatment.

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.
