Ischemic monomelic neuropathy after thoracic endovascular aortic repair (TEVAR) : Case Report

Abstract

Ischemic monomelic neuropathy (IMN) is a rare type of peripheral neuropathy presenting with sensory and motor impairment after vascular surgery.1 It is particularly rare for one to experience IMN following thoracic endovascular aortic repair (TEVAR); however, we have recently experienced such a case. A 56-year-old male with traumatic aortic dissection underwent TEVAR. One day after, he suddenly complained of numbness of the left hand with reduced grip strength and wrist movement. Upon physical examination, weak left radial arterial pulse and significantly low blood pressure in the left arm (85/60 mmHg) compared to right arm (130/85 mmHg) were observed. Electrophysiologic findings were compatible with left radial, median and ulnar neuropathy. On follow-up 1 year later, his motor weakness was mildly improved, but constant neuropathic pain and ulnar claw deformity were observed.
