Latest evidence on chimney endovascular repair of abdominal aortic aneurysms and the renal artery angulation pitfall

J Cardiovasc Surg (Torino). 2024 Apr;65(2):119-123. doi: 10.23736/S0021-9509.24.12936-9. Epub 2024 Apr 15.

Abstract

This article summarizes the key findings in literature up to date on the endovascular treatment of complex abdominal aortic aneurysms (AAAs) employing the chimney technique. Additionally, an unexplored pitfall is described regarding the target vessel angulation. Although balloon-expandable covered stents present more favorable configuration in downward-oriented target vessels, transverse and upward-oriented target vessels may benefit from other endovascular techniques imploring careful case planning and further investigation on the topic.
