主动脉夹层临床分型与预后的关系

目的回顾分析A、B两型主动脉夹层的病因、并发症及对预后的影响。方法总结分析本院13年来收治主动脉夹层患者105例。结果A型54例(51.4%),B型51例(48.6%)。B型主动脉夹层患者住院病死率显著低于A型(分别为12%和28%,P<0.05)。A型患者心包积液的发生率显著高于B型(33.3%和13.7%,P<0.05)。心脏压塞的发生率A型高于B型,但差异无统计学意义。B型患者一过性肾功能受损的发生率显著高于A型(分别为47.1%和22.2%,P<0.01)。结论B型主动脉夹层患者的预后较A型者好。

Effects of Clinical Classification on Prognosis of Aortic Dissection

Objective: To analyze the cause, complication and prognosis of type A and type B aortic dissection (AD) retrospectively. Methods: One hundred and five cases with AD hospitalized in our hospital in recent 13 years were analyzed. Results: Fifty-four cases ( 51.4% ) were type A and 51 cases ( 48.6% ) were type B. In-hospital mortality rate of type B AD patients was significantly lower than that of type A AD patients (12% versus 28%, P< 0.05 ). The occurrence rate of pericardial effusion was significantly higher in patients with type A than that of in type B ( 33.3% versus 13.7% , P< 0.05 ). The occurrence rate of cardiac tamponade in type A was higher than that of in type B, but there was no statistic difference. The occurrence rate of transient renal dysfunction was significantly higher in type B patients than that of in type A patients ( 47.1% versus 22.2% , P< 0.01 ). Conclusion: Patients with type B AD have better prognosis than patients with type A AD.
