Hypothermic circulatory arrest is used for proximal and total aortic arch correction in patients with aortic arch aneurysm and acute or chronic type A aortic dissection. Different cerebral perfusion techniques have been proposed for reducing morbidity and mortality rate. The study of Arnaoutakis et al. showed that deep hypothermic circulatory arrest with or without retrograde cerebral perfusion for proximal aortic aneurysm and acute type A aortic dissection correction had similar results with regard to morbidity and mortality rate. In addition, the short circulatory arrest time contributes for favorable outcomes of these patients. Although antegrade cerebral perfusion with hypothermic circulatory is widely used by many cardiac surgeons, deep hypothermic circulatory arrest with or without retrograde cerebral perfusion remains an alternative and safe method for brain protection in patients undergoing proximal aortic arch aneurysm or acute type A aortic dissection repair.
深低温停循环用于治疗主动脉弓动脉瘤和急性或慢性 A 型主动脉夹层的近端和全主动脉弓矫正。已经提出了不同的脑灌注技术来降低发病率和死亡率。Arnaoutakis 等人的研究表明，对于近端主动脉瘤和急性 A 型主动脉夹层的矫正，深低温停循环伴或不伴逆行性脑灌注对发病率和死亡率的结果相似。此外，短时间的停循环有助于这些患者的预后良好。尽管低温停循环的顺行性脑灌注被许多心脏外科医生广泛使用，但深低温停循环伴或不伴逆行性脑灌注仍然是一种替代方法，也是在进行近端主动脉弓动脉瘤或急性 A 型主动脉夹层修复的患者中保护大脑的安全方法。
