Local sympathetic denervation by surgical sympathectomy is used in the treatment of lower limb ulcers and ischemia,but the restoration of cutaneous sympathetic nerve functions is less *** study aims to explore the recovery of cutaneous sympathetic functions after bilateral L2-4 *** skin temperature of the left feet,using a point monitoring thermometer,increased intraoperatively after *** cytoplasm of sympathetic neurons contained tyrosine hydroxylase and dopamineβ-hydroxylase,visualized by immunofluorescence,indicated the accuracy of *** starch test results suggested that the sweating function of the hind feet plantar skin decreased 2 and 7 weeks after lumbar sympathectomy but had recovered by 3 *** and western blot assay results revealed that norepinephrine and dopamineβ-hydroxylase expression in the skin from the sacrococcygeal region and hind feet decreased in the sympathectomized group at 2 *** electron microscopy results showed that perinuclear space and axon demyelination in sympathetic cells in the L5 sympathetic trunks were found in the sympathectomized group 3 months after *** sympathetic denervation occurred in the sacrococcygeal region and hind feet skin 2 weeks after lumbar sympathectomy,the skin functions recovered gradually over 7 weeks to 3 *** conclusion,sympathetic functional recovery may account for the recurrence of hyperhidrosis after sympathectomy and the normalization of sympathetic nerve trunks after incomplete *** recovery of sympathetic nerve function was slower in the limbs than in the torso after bilateral L（2-4） sympathectomy.
