Rupture of an iliac artery during percutaneous transluminal angioplasty is rare, but can be life threatening. When arterial rupture occurs, the site should be tamponaded with the angioplasty balloon and plans should be made for surgical repair of the artery. In most situations, operating room preparation time requires at least 30 to 60 minutes. Repeat angiography should be performed just prior to surgery since successful hemostasis at the rupture site may obviate surgery. We report the second case in the literature in which haemorrhage from such a rupture was successfully treated using angioplasty balloons thus preserving the successful angioplasty and avoiding surgical intervention without ever subjecting the patient to undue risks. © 1989.
