[Post-traumatic aneurysm of the ulnar artery--a report of 2 cases].

Two cases of post-traumatic aneurysms of the ulnar artery within the hand in patients aged 28 and 45 years are presented. First one developed following blunt trauma of the hypohtenar during use of the screwdriver, other one was caused by puncture, penetrated injury. Both were typically localised at the base of the hypothenar and both were asymptomacic. Presence of the pulsating tumour in the palm was a cause of the medical appointment. Arteriography was performed in both cases that confirmed diagnosis of the aneurysm. Patients were operated on 2 months after initial injury. The aneurysm was resected and ulnar artery was re-anastomosed by vein graft in one case, and by direct suture in the other one. Anticoagulants were administered post-operatively. In both cases the course was uneventful, and phone call one year after operation revealed only some symptoms of cold intolerance in one patient. The likelihood of aneurysm formation as a consequence of blunt and sharp trauma of the hand was suggested as well as the necessity of prompt diagnosis and operative treatment.
