The Effect of Sympathectomy for Essential Hypertension on the Hallucal Circulation

The effects of sympathectomy on the hallucal circulation were studied in patients with essential hypertension. Return of sympathetic nerve function of variable degree could be demonstrated in every patient. An increase in non-neurogenic or intrinsic resistance was also found to be attributable to the sympathectomy. This could not be reversed by benzodioxane and was therefore probably not produced by circulating epinephrine. The possible mechanisms of this phenomenon are discussed.
