True posttraumatic radial artery aneurysm

Abstract

Radial artery aneurysms are rare and mostly secondary to traumatic events (posttraumatic pseudoaneurysms). Radial artery aneurysms should be treated due to the high risk of embolization, thrombosis, and compression of adjacent nerves. The authors describe a case of a 49-year-old patient complaining of a progressively growing tumor in the left wrist after a dog bite. The tumor proved to be a true posttraumatic aneurysm. Treatment consisted of removal of the aneurysm sac and ligation of the radial artery.
