Technical considerations in endovascular repair of large symptomatic iliac anastomotic aneurysms.

In comparison to endovascular repair of fusiform iliac aneurysms, endovascular repair of large iliac anastomotic aneurysms can be difficult because of their saccular nature and redundancy of the iliac limb of the prosthetic graft. Iliac anastomotic aneurysms may have patency of ipsilateral hypogastric artery branches necessitating coil embolization. We report technical challenges incurred in two patients during endovascular repair of large symptomatic iliac anastomotic aneurysms.
