Traumatic pseudoaneurysm in an ulnar artery vein graft

Ulnar artery thrombosis is well reported but treatment recommendations still vary. We report the 10-year follow-up of a vein graft used to treat a patient with ulnar artery thrombosis. The graft remained patent until the tenth year, when the patient sustained a blunt hyperextension injury to the involved wrist and developed a pseudoaneurysm of the vein graft. The pseudoaneurysm was found to be in the graft itself and not at the anastomosis. The vein graft thrombosed and was successfully treated with resection of the thrombosed vessel, embolectomy of the superficial palmer arch, and replacement with a new vein graft.
