Pre-constrain technique using the Gore Excluder Conformable endograft for abdominal aortic aneurysm with severely angulated proximal neck

Abstract

Endovascular aneurysm repair for abdominal aortic aneurysms with a severely angulated proximal neck remains challenging because of the higher rates of type 1a endoleaks and secondary interventions. In this study, we reviewed six consecutive patients with a severely angulated proximal neck (>60°) treated with endovascular aneurysm repair at a single center. They were treated with a Gore Excluder Conformable endograft using a pre-constrain technique to prevent type 1a endoleaks. It is the unique deployment technique of the proximal trunk by pre-constrain of the proximal edge. This technique helps obtain optimal deployment of the proximal main body.
