Open distal anastomosis technique in acute type A aortic dissection

Background Acute ascending aortic dissections is the most common catastrophe of the aorta that requires emergency surgery. There is still a debate regarding the optimal surgical approaches for construction of the distal anastomosis in replacing the ascending aorta. The purpose of this study was to evaluate early clinical outcomes of two different surgical techniques: open distal anastomosis in hypothermic circulatory arrest (OHCA) compared to anastomosis with clamped aorta while continuing on extracorporeal circulation (CECC).
