急性主动脉夹层与脑灌注不足

Acute aortic dissection and cerebral malperfusion

合并有脑灌注不足的急性主动脉夹层（acute aortic dissection,AAD）诊断依然是临床上的一个重大问题,尤其是早期诊断关系着患者的预后。国际记录数据显示,在2 202例AAD患者中,有132例（6%）合并脑卒中[1]。现有资料显示AD急性期意识障碍发生率达20%[2],

Cerebral ischemia associated with acute aortic dissection is not common,it is hard to decide direction between nervous system and cardiovascular system.This paper reviws the mechanism of cerebral malperfusion caused by acute aortic dissection,introduces a number of methods that are helpful to diagnosis acute aortic dissection,emphasizes the importance of early diagnosis especially pre-hospital diagnosis,proposes portable echocardiography,and presents cureent situation and expectation.
