Snorkel/chimney and fenestrated endografts for complex abdominal aortic aneurysms.

Snorkel/chimney and fenestrated endografts for complex abdominal aortic aneurysms. journal of cardiovascular surgery Ullery, B. W., Lee, J. T., Dalman, R. L. 2015; 56 (5): 707-717

Abstract

Complex endovascular aneurysm repair (EVAR) involves extension of the proximal aortic seal zone with preservation of branch vessel patency, thereby expanding the applicability of endografting from the infrarenal to the suprarenal aorta. Snorkel/chimney (Sn-EVAR) and fenestrated EVAR (f-EVAR) serve as the two most commonly utilized advanced endovascular techniques to combat hostile proximal neck anatomy. The purpose of this article is to describe the principles and evolution of these advanced endovascular strategies, technical considerations, and results of sn- and f-EVAR in the management of challenging neck anatomy in abdominal aortic aneurysm disease.
