Abstract

In this case, we describe a case of a 76-year-old male with extensive aortoiliac aneurysms treated by endovascular aneurysm repair using the sandwich technique in order to preserve left internal iliac artery perfusion. The sandwich technique refers to the deployment of multiple paralleled stent grafts into main distal and side branches in overlapping with a single proximal stent graft. The procedure was successfully performed without complications. Post-procedural CT angiography demonstrated patent stent grafts without any endoleak. The strengths and limitations of the sandwich technique need to be investigated in large-scale, long-term clinical trials.

  Fig. 1 Abdominal aortic aneurysm with bilateral common iliac artery involvement

  Fig. 2 A Viabahn (8×150 mm) stent graft is inserted to the left internal iliac artery (IIA) through the left brachial artery and an iliac extender (Excluder 12-14) stent graft is deployed in the left external iliac artery through the Lt. common femoral artery sheath. An angiography shows proper positions of the deployed stent grafts with good blood flow to the left IIA and minimal endoleaks (type Ib and III). Follow-up aorta CT scans taken at 3 days after the procedure shows patent stent grafts without significant endoleak.
