Aortic wall degeneration late after ascending aortic wrapping.

Abstract

Little is currently known about the pathological changes after aortic wrapping. This study investigated long-term outcomes including pathological findings after ascending aortic wrapping. Of the 30 patients who underwent aortic wrapping from 2004 to 2012, redo surgery was later performed in six patients. All the patients underwent ascending aorta replacement because of safety issues associated with aortic cross clamping due to adhesion. Pathologically, the tunica media had been lost and replaced by foreign body granulation. The wrapped aorta manifested severe erosion late after surgery. The wrapped aorta will likely be replaced in a redo surgery.
