Abstract
TWO types of study are commonly employed in evaluating the physiologic effectiveness of sympathetic denervation of the extremities: those methods based on the presence or absence of sweating in the area denervated and those based on the presence or absence of vasoconstrictor activity in the denervated area.The present report deals with an evaluation of the vasoconstrictor activity in extremities after a number of different operations on the sympathetic pathways to the extremities and a comparison of these physiologic effects with the clinical results in a group of patients having intact peripheral main-vessel circulation before and after operation. The vasoconstrictor . . .
