An Experimental Study on Transplantation of the Aortic Arch

Part. I. An Experimental Study on Interruption of the Ascending Aorta

Abstract

In case the ascending aorta is interrupted, the clamped site will rupture prior to heart failure due to rapid overload on the heart regardless under normo or hypothermia.
Under severe hypothermia, it will, however, tolerate long cessation due to remarkable decrease of burden on the heart. Most of the cases could be successfully resuscitated after the aorta alone is interrupted or the inflow and outflow tract are -both obstructed at the same time. In case the ascending aorta is divided and reanastomosed, performance of operation is difficult and the main fatal cause is massive bleeding from the anastomosis.
