<b>Improvement in Proximal Aortic Endograft Fixation</b>: An Experimental Study Using Different Stent-Grafts in Human Cadaveric Aortas

Abstract

The Zenith stent-graft had the best resistance to dislodgment. An additional Palmaz stent placed at the proximal attachment site greatly improves endograft fixation regardless of the type of stent-graft. For complex aneurysm necks or for intraoperative type I endoleak management, an adjunctive Palmaz stent could be used.
