Abstract
A 71-year-old patient with high-output cardiac failure was found to have an aneurysmal distal aorta with evidence of an arteriocaval fistula on ultrasound scanning. CT demonstrated an aneurysm of the distal aorta and right common iliac artery and an intraarterial digital subtraction angiogram confirmed an arteriocaval fistula. In view of the patient’s cardiac failure and general condition an endovascular stent was considered. The right internal iliac artery was occluded with Tungsten coils prior to the insertion of a bifurcated stent-graft. This resulted in total occlusion of the aneurysm and obliteration of the arteriocaval fistula. To our knolwedge such a case has not been previously reported.
