目的:探讨急性主动脉夹层的预测死亡的危险因素。方法:采用回顾性分析方法分析1995~2006年资料完整的67例主动脉夹层病例,使用Logistic回归分析年龄、性别、病因、临床症状及体征、治疗方法的选择与急性主动脉夹层的临床病死率的线性关系。结果:①总体临床病死率为14.90%。其中按Stanford分型,Stan-fordA型患者临床病死率为18.75%,StanfordB型患者临床病死率为11.40%。②Logistic回归分析示神经系统症状(P=0.0166)、心包积液(P=0.0183)、局部肢体缺血(任一肢体)(P=0.0407)为急性主动脉夹层预测死亡的危险因素。结论:神经系统症状、心包积液、局部肢体缺血为急性主动脉夹层的独立死亡危险因素。
Objective: To investigate the risk factors of death in acute aortic dissection. Methods: A retrospective analysis method was used to analyze 67 cases of aortic dissection with complete data from 1995 to 2006. Logistic regression was used to analyze the age, sex, etiology, clinical symptoms and signs, the choice of treatment method and the clinical mortality of acute aortic dissection The linear relationship. Results: ① The overall clinical mortality was 14.90%. According to Stanford classification, Stan-fordA patients with clinical mortality was 18.75%, StanfordB type clinical mortality was 11.40%. Logistic regression analysis showed that neurological symptoms (P = 0.0166), pericardial effusion (P = 0.0183), and local limb ischemia (both limbs) (P = 0.0407) were risk factors for predicting mortality in acute aortic dissection. Conclusion: Neurological symptoms, pericardial effusion, and local limb ischemia are risk factors for independent death of acute aortic dissection.
