Technique of slow deployment of Gore Excluder endograft improves accuracy of placement.

Abstract

The standard deployment of Gore Excluder endoprostheses involves rapid pulling of the deployment knob once the graft is thought to be properly positioned. We describe an alternative technique that involves the slow pulling of the deployment knob. The key features of this technique include anticipating the asymmetric flowering of the graft that occurs toward the contralateral limb, prompt correction of any graft malpositioning, and maintaining the slow deployment until the contralateral gate is released. Our experience with this technique demonstrates that it is accurate, safe, and reduces the need for proximal extension cuffs.
