Treatment of type I endoleak in an iliac aneurysm with balloon expandable palmaz stent

Abstract

Endovascular exclusion of the peripheral arterial aneurysms with covered stent grafts have been used to decrease the operative morbidity and mortality in comorbid old patients. However, endoleaks remain a problem. The authors present a case of left common iliac artery aneurysm, which was treated by endovascular therapy. Initially, internal iliac artery was occluded with coil embolization to prevent type II endoleak. A covered self-expandable stent was used for exclusion of the aneurysm. A proximal perigraft leak was detected in control contrast injection. Palmaz balloon expandable stent was used for treatment of proximal perigraft leak. The control angiography showed complete exclusion of the aneurysm and no perigraft leak was detected in the aneurysm sac. Proximal balloon expandable stent implantation as an addition to covered stent in short and angulated necked aneurysms is technically feasible, and this technique provide a good treatment method for proximal perigraft leak.
