Modification of the Viabahn Open Revascularization Technique for extensive internal iliac artery aneurysms

Abstract

We modified the Viabahn Open Revascularization Technique for managing extensive internal iliac artery aneurysms concomitant with aortoiliac aneurysms to facilitate the proximal suture with the exclusion of internal iliac artery aneurysms. Preceding open surgery, deployment of the Viabahn stent graft in the superior gluteal artery with coil embolization of the iliolumbar and inferior gluteal arteries was performed. Subsequently, during open surgery, a direct anastomosis between the vascular graft and the Viabahn stent graft was performed. Notably, extensive dissection around the internal iliac arteries was not required. Postoperative computed tomography angiography revealed the patent internal iliac artery branches and complete exclusion of the extensive aneurysms.
