Rapid Expansion of Occluded Common Iliac Arterial Aneurysm Following Endovascular Treatment

Abstract

A 74-year-old man presented with intermittent claudication in his right leg. Endovascular treatment using metallic stents was performed for occlusion of his right common iliac arterial aneurysm and right external iliac artery. Soon after endovascular treatment, the aneurysm rapidly increased in size and a diagnosis of impending rupture was made. He was treated surgically using a bifurcated graft. Metallic stenting is a risky treatment in cases with ischemia caused by thrombosed aneurysm.
