Endovascular Repair with GORE VIABAHN for Pseudoaneurysm after Endovascular Treatment of Occluded Iliac Artery

Abstract

A 68-year-old man suffered from bilateral critical limb ischemia due to occlusion of the bilateral iliac and bilateral superficial femoral arteries after undergoing Hartmann’s operation for rectal cancer. We performed endovascular therapy for the bilateral iliac arteries using self-expandable bare-metal stents. During the procedure for the left iliac artery lesion, a guide-wire passed through the subintimal plane, proximal to the adventitia. Follow-up computed tomography revealed a pseudoaneurysm of the left common iliac artery and external iliac artery, in which contrast staining was observed outside the stents. We performed a stent-graft placement using GORE VIABAHN for the left iliac artery. Postoperative contrast-enhanced computed tomography revealed regression of the left iliac artery pseudoaneurysm. Postoperative imaging surveillance is necessary when subintimal angioplasty was performed, particularly, in case of a guide-wire passing via adventitia. GORE VIABAHN is useful for treating iliac pseudoaneurysms after endovascular treatment.
