摘要
Circulation arrest is widely used during total aortic arch replacement. However, the conventional procedures have high morbidity and mortality. We modified the hybrid procedure by optimizing the sequence of anastomosis between the graft and aorta. As a result, the time of extracorporeal circulation was obviously shortened, and cardiac arrest was needed only during the two anastomoses of the aorta with aorta graft main body. In addition, both circulation arrest and deep hypothermia were avoided. Leakage was also prevented by creating a lengthened sealing zone for stent graft deployment.
