Hybridizing the "Sandwich" and "Chimney" Techniques in the Endovascular Repair of Coarctation of the Aortic Arch and Postcoarctation Ectasia Concomitant with a Left Subclavian Artery Aneurysm

Abstract

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case, we describe a 51-year-old patient who presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up.
