Parallel Grafts to Treat Aorto-iliac Aneurysms: How to Size the Common Iliac Stent Graft

Aortoiliac aneurysms (AIA) occur unilaterally or bilaterally. Up to 40% of abdominal aortic aneurysms (AAAs) are associated with iliac artery aneurysms.[1] One technique to preserve internal iliac artery (IIA) blood flow is the sandwich technique (ST),[2] using two covered stents – one to the IIA, and the second to the external iliac artery (EIA) – which are placed inside the common iliac stent graft (the main limb of endovascular aneurysm repair; Fig 1.) It is very important to choose the correct sizing of common iliac stent grafts to decrease risk of type 3 endoleak.[3 ]
