摘　　要：急性A型主动脉夹层是一种危及生命的疾病,起病急、进展快、病死率高。目前诊断急性A型主动脉夹层最快速、最准确的方法是主动脉强化CT扫描,其敏感性和特异性均非常高,但仍缺乏有效准确预测主动脉夹层发生风险的方法。本文对已有文献进行综述,发现升主动脉形态对预测A型主动脉夹层发生风险具有重要的作用。通过比较主动脉直径与主动脉其他形态在预测主动脉夹层发生风险的价值,讨论如何应用主动脉强化CT评估主动脉夹层的发生风险。Acute type A aortic dissection(ATAAD) is a life-threatening medical emergency that carries acute onset,rapid progress and high mortality rate.At present,the fastest and most accurate method for the diagnosis of acute type A aortic dissection is CT angiography(CTA),which has high sensitivity and specificity.But there are still no effective and accurate methods to predict aortic dissection.Reviewing the related papers shows that the aortic morphology plays an important role in predicting type A aortic dissection.By comparing the role of aortic diameter and other shapes of aorta in predicting the risk of aortic dissection,this paper discusses how to use CT angiography(CTA) to expand the existing risk assessment methods of aortic dissection.
