title: The 'docking maneuver' for Gore Excluder positioning in the treatment of abdominal aortic aneurysms with an ectatic neck.
abstract: The aim was to present a technical modification to the 'funnel technique' that allows endovascular repair of infrarenal abdominal aortic aneurysms with an ectatic neck. The body of the Excluder endograft is opened inside the aneurysm, using the slow deployment technique, stopping as soon as the contralateral limb is open. The gate is cannulated in the usual fashion. A percutaneous transluminal angioplasty (PTA) balloon is introduced in the contralateral limb and inflated to nominal pressure. By pulling the introducer of the Excluder delivery system on one side and the PTA balloon on the other, the graft is positioned on the bifurcation with the contralateral leg inside the common iliac artery. At this point, the ipsilateral iliac leg is deployed and the thoracic endograft can be positioned through the abdominal component. Finally, the contralateral iliac leg is deployed. The technique described offers a simple method to treat aortic abdominal aneurysms with an ectatic neck by positioning a bifurcated abdominal graft in such a way that subsequent insertion of the thoracic component is facilitated.
