The aim of the study was to evaluate the anatomic suitability for endovascular abdominal aneurysm repair (EVAR) according to instructions for use (IFUs) of three commercially available bifurcated stent graft devices and explore the possible benefits of low-profile delivery systems. Computed tomography scans of 241 patients with abdominal aortic aneurysm (AAA) were evaluated for suitability of Zenith Flex, Gore Excluder and Endurant bifurcated stent graft systems according to their IFUs.

Endovascular abdominal aortic aneurysm repair (EVAR) in patients with unfavorable proximal seal zones remains challenging. The purpose of this study was to identify the incidence of proximal extension cuff usage for type I endoleaks in patients with abdominal aortic aneurysms and unfavorable necks treated with the C3 Excluder repositionable endoprosthesis compared with the traditional Excluder stent-graft.

Between December 1998 and June 2010, 121 nonconsecutive patients underwent insertion of a GORE EXCLUDER stent-graft to treat an aortic (n=80; 66%), aortoiliac (n=25; 21%), or isolated common iliac (n=16; 13%) aneurysm. Procedural and follow-up data were collected prospectively. Primary endpoints are overall survival, intervention-free survival, and freedom from aneurysm rupture. Secondary endpoints are device- and procedure-related complications, including all types of endoleaks or endotension, and reintervention

Several tips are presented to achieve effective and durable fixation and sealing of Excluder stent-grafts in abdominal aortic aneurysms (AAA) with challenging necks. The primary approach to patients with short infrarenal necks is a slow and controlled deployment combined with the bending-the-wire technique to realign the axis of the aneurysm and the axis of the neck. Severe infrarenal neck angulation is dealt with by bending the guidewire, orienting the iliac limbs of the Excluder in the anteroposterior direction, and using the slow and controlled endograft deployment technique. Other key procedural factors, such as using the percutaneous approach and local anesthetic, reorienting the stent-graft, using Excluder aortic extensions, employing the endowedge and kilt techniques, and using the appropriate C-arm angulation to adequately visualize the target landing zone, are also useful.
