Ulnar Artery Thrombosis in Guyon's Canal

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.
