Embolization of a false aneurysm fistulized to the contralateral common iliac artery. A case report.

We describe a patient who developed a false aneurysm interposed between bilateral common iliac arterial stumps 6 years after replacement of a bifurcated graft for repair of abdominal aortic aneurysm. The false aneurysm formed a fistula to the contralateral common iliac artery stump. In the light of this patient's history of severe arterial disease, weakness of the arterial wall was thought to be responsible for this anastomotic false aneurysm. Due to significant risk factors, the patient was treated with transcatheter intervention and he recovered without complications.
