对于12名患者（70.59%），体外循环建立通过右腋动脉插管且选择性顺

For 12 patients (70.59%), cardiopulmonary bypass was established via right axillary artery cannulation and selective antegrade cerebral perfusion was performed (of which 1 was combined with femoral artery cannulation), and 4 (23.53%) with cardiopulmonary bypass The ascending aorta was cannulated, and selective antegrade cerebral perfusion was performed by deep insertion of the cannula into the innominate artery (of which 2 were combined with femoral artery cannulation), and 1 patient (5.88%) with extracorporeal circulation was established through the artery Intubation and selective antegrade cerebral perfusion are performed by direct intubation in the right common carotid artery.

For 12 patients (70.59%), in vitro circulation was established through the right arterial intubation and selective flow of brain perfusion was carried out (of which 1 combined femoral artery intubation), 4 (23.53%) had in vitro circulation established through an aortic intubation intubation, and selective flow ingressin was carried out by inserting the intubation deep into the unknown artery (of which 2 merged feline intubite), 1 patient (5.88%) had an in vitro circulation through the in vitro circulation. And selective flow brain perfusion is carried out through direct intubation in the right neck artery.

For 12 patients (70.59%), cardiopulmonary bypass was established by right axillary artery intubation and selective antegrade cerebral perfusion was performed (one of them was combined with femoral artery intubation), 4 patients (23.53%) had cardiopulmonary bypass established by ascending aorta intubation and selective antegrade cerebral perfusion was performed by deep insertion of the intubation into innominate artery (two of them were combined with femoral artery intubation), 1 patient (5 88% of the patients with CPB were intubated by artery, and the selective antegrade cerebral perfusion was performed by direct intubation in the right common carotid artery.<br>
