Abstract

Carpal tunnel syndrome can be produced by abnormal mass effect due to trauma, ganglion cysts, various soft tissue tumors, musculotendinous variants, and aberrant vascular structures. Persistent median artery is one of the causes of the carpal tunnel syndrome. Thrombosed persistent median artery usually accompanies the anomaly of the median nerve and causes a sudden onset of severe pain and paresthesia. In contrast to previous literature, we report the rare case of gradual onset and mild symptom of a 53-year-old man with a thrombosed persistent median artery but without anomaly of the median nerve and abnormal finding of electrophysiologic study.
