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

Norepinephrine depletion commonly is the desired effect, other neurotransmitters (eg ATP, NPY and enkephalins) are depleted by sympathectomy
The term Sympathectomy used in this discussion refers mainly to the lesioning of postganglionic noradrenergic (NA) neurons and fibers except where noted. Although norepinephrine depletion commonly is the desired effect, other costored neurotransmitters (eg ATP, NPY and enkephalins) are depleted by sympathetic denervation. The multitude of research studying the effects of sympathetic loss is made possible by the morphologically defined anatomy of the postganglionic sympathetic chains, the sensitivity of postganglionic NA neurons to nerve growth factor (NGF) deprivation, and the phenotypic specialty of these neurons that allows for the selective uptake of neurotoxins.
