Abstract
Objective To discuss the pathological characteristics and treatment options of medial nerve injury after percutaneous brachial artery puncture. Methods From January 2015 to June 2016, 4 cases of median nerve injury were admitted in our department. The patients'age ranged from 57 to 76 years. Time from onset of symptoms to office visit ranged from 5 days to 1 year. Median nerve injury was identified with physical examination, ultrasound, angiography and electrophysiological examination. One case was treated conservatively. The other 3 cases were treated with surgical neurolysis. Results One case had hematoma compression. One case had hematoma compression and direct puncture of the nerve. One case had arteriovenous fistula compression. And pseudoaneurysm compression was identified in the last case. The outcomes were poor in all 4 cases. Conclusion Median nerve injury is one of the most serious complications of percutaneous brachial artery puncture. This procedure should be guided with ultrasound. Carefulness in the procedure and proper postoperative treatment may lead to fewer complications. Early recognition and surgical intervention is vital to the restoration of nerve function. Key words: Median nerve; Brachial artery; Punctures; Complications
