“…Although sympathectomy with clips 5 and the section of the rami communicantes (ramicotomy) and Kuntz nerve 6 have been proposed, selective bilateral sympathectomy (excision of sympathetic trunk, rami communicantes, and ganglia) seems to have the best effectiveness with total satisfaction of patients. 7 Black et al, 8 in 233 endoscopic sympathectomies with laser, revealed 0.85% bleeding, 0.43% pulmonary edema, and 0.85% failed procedure. Chang et al, 9 reevaluating retrospectively 234 patients treated with sympathectomy of T2, T3, T4 for palmar hyperhidrosis, displayed the compensatory sweating (CS) incidence of 92% T2, 92% T3, and 80% T4.…”
