Abstract

Causes of ulnar nerve compression in Guyon's canal are various, but thrombosis of the ulnar artery due to a single trauma is rarely reported. We report a case of ulnar nerve compression caused by traumatic thrombosis of the ulnar artery in Guyon's canal. Surgical excision of the ulnar artery thrombus and end to end anastomosis resulted in complete relief of the patient's symptoms.

  Fig. 1. Doppler ultrasonography. (A) Transverse scan and (B) longitudinal scan show a 1.2 cm sized low echogenic mass that press on ulnar nerve. (C) Transverse scan shows eccentrically locating thrombus in ulnar artery with preserved blood flow. T, thrombus; A, ulnar artery; N, ulnar nerve.

  Fig. 2. Intraoperative photography shows oval-shaped mass on ulnar artery. This mass compress and adherent to ulnar nerve.
