Key result
A new endovascular procedure using a combined chimney-graft/double-barrel technique was reported to exclude bilateral common iliac artery aneurysms while preserving blood flow to one internal iliac artery.
Case Report
This novel endovascular technique offers a way to treat bilateral common iliac artery aneurysms while preserving internal iliac artery flow, avoiding the need for open surgery.
May offer an endovascular alternative for bilateral iliac aneurysms with internal iliac preservation; leaves open safety, durability, and broader applicability.
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.

Frigatti et al. (2010) conducted a case report in Bilateral common iliac artery (CIA) aneurysms. Combined 'chimney-graft/double-barrel' endovascular procedure was evaluated. A new endovascular procedure using a combined chimney-graft/double-barrel technique was reported to exclude bilateral common iliac artery aneurysms while preserving blood flow to one internal iliac artery.
