A 59-year-old man with no prior neurological deficits developed a massive stroke during the repair of a double-barreled acute type A aortic dissection with major entry in the ascending aorta and an occluded brachiocephalic artery. As right cerebral ischemia was alleviated by the circle of Willis, the patient was alert and conscious preoperatively. Nevertheless, the thrombus in the right carotid artery induced a severe postoperative right cerebral embolism. In conclusion, occlusion of the carotid artery is a risk factor of postoperative severe stroke, even in patients without neurological symptoms preoperatively.
一名59岁既往无神经功能缺损的男性,在修复升主动脉有主要破口且头臂动脉闭塞的双腔急性A型主动脉夹层时发生大面积卒中。由于Willis环缓解了右侧脑缺血,患者术前神志清醒。然而,右侧颈动脉内的血栓导致了严重的术后右侧脑栓塞。总之,颈动脉闭塞是术后严重卒中的一个危险因素,即使是术前没有神经症状的患者。
