IntroductionTotal aortic arch repair represents a high-risk operation and may compromise the surgical decision due to the increased mortality and cerebral complications. The arch first technique with retrograde cerebral perfusion or selective antegrade cerebral perfusion was introduced to extend the safety period from cerebral ischemia during deep hypothermic circulatory arrest. However, profound hypothermia prolonged the myocardial ischemic time and cardiopulmonary bypass (CPB) time, and induced coagulopathy which resulted in deteriorated myocardial function, end-organs dysfunction and excessive postoperative bleeding, 1) and the complex manipulation of antegrade cerebral perfusion may release debris from endo-clamping or snaring of arch vessels and the clustered tubes interrupted the operative field. Our modified four-branched graft technique for arch surgery had been reported in 2012, with advantages to evade selective antegrade cerebral perfusion and deep hypothermia.
