A New Endovascular Approach to Exclude Isolated Bilateral Common Iliac Artery Aneurysms

Abstract

A new endovascular procedure is reported to treat bilateral common iliac artery (CIA) aneurysms extending to both iliac bifurcations.The left internal iliac artery (IIA) was first embolised, two overlapped Viabahn endografts were delivered from the right IIA to the distal aorta and, finally, CIA aneurysms excluded using iliac contralateral leg and extension endografts from the distal aorta to both external iliac arteries, applying a combined ‘chimney-graft/double-barrel’ technique.This procedure may extend the limits of conventional iliac endografting by preserving blow flow to at least one IIA using off-label commercially available devices, avoiding associated open surgical procedures.
