Fracture and embolization of a metal stent after a frozen elephant trunk procedure

Abstract

Abstract The Frozenix J graft open stent graft has been available since 2014 in Japan. This stent is widely used for the frozen elephant trunk technique in many institutions, mainly for cases of acute type A aortic dissection and also for cases of a true aneurysm and chronic aortic dissection. We treated a rare case in which the metal wires of the Frozenix J graft were broken and embolized to the periphery half a year after being implanted.
