The trifurcated endograft technique for hypogastric preservation during endovascular aneurysm repair.

Bilateral common iliac artery involvement remains a significant challenge for endovascular aneurysm repair. We describe a technique to overcome this obstacle that we have termed the trifurcated endograft. The technique involves the deployment of a second bifurcated endoprosthesis into an iliac limb to create a three-limbed graft. The third limb is then used as the origin for an extension into one hypogastric artery.
