Aneurysms of the digital artery: a review and report of three cases.

Aneurysms of the digital artery are rare. Since 1980, we have treated three traumatic aneurysms of the digital artery. There were two lesions of the common palmar digital artery and one of the ulnar pollicis artery. One case was caused by a traumatic laceration with a kitchen knife, and two cases were caused by repetitive microtrauma. On histologic examination, there were two true aneurysms and one false aneurysm. Two cases were treated by excision only, and one case was treated by excision and reanastomosis. The operating microscope was useful during neurolysis, excision of the aneurysm, and vascular anastomosis.
