急性主动脉夹层动脉瘤危及生命,及时准确的诊断和治疗对挽救生命起决定性作用。未治疗者每小时死亡率为1％,而早期治疗可明显降低病人死亡率。Stanford将主动脉夹层动脉瘤分两型:A型:夹层累及升主动脉。B型:不累及升主动脉。A型相当于DeBakeyⅠ、Ⅱ型,B型相当于Ⅲ型。手术可改善A型病人的预后,而无并发症的B型患者用药物治疗也可获得良效。 Acute dissecting aneurysms life-threatening, timely and accurate diagnosis and treatment play a decisive role in saving lives. The rate of death per hour for untreated persons was 1%, whereas early treatment significantly reduced patient mortality. Stanford Aortic dissection will be divided into two types: A type: dissection involving the ascending aorta. Type B: not involving the ascending aorta. A type is equivalent to DeBakey Ⅰ, Ⅱ type, B type is equivalent to Ⅲ type. Surgery can improve the prognosis of type A patients, but no complications of type B patients with medication can also be effective.
