[Acute occlusion of the iliac arteries due to blunt trauma].

Two cases of acute iliac occlusion due to blunt trauma are presented. The cause of injuries were a fall from bicycle in case 1 and a compression between an automobile and a wall in case 2. The end-to-end anastomosis was possible in case 2, but an interposition of an artificial prosthesis was necessary because of the length of damaged artery in case 1. Both cases were associated with the pelvic fracture, adding the perforation of small bowels and the bladder in case 2. Postoperative course was almost uneventful except fasciotomy was needed for the compartment syndrome of the right lower extremity in case 2.
