The utility of transthoracic two-dimensional echocardiography in patients with aortic dissection was assessed by retrospective analysis in 67 patients: 31 patients with DeBakey type I, 21 patients with type II, 10 patients with type III, and five patients with false-positive diagnoses. Aortic dissection was correctly identified by two-dimensional echocardiography in 49 patients; 13 had false-negative diagnoses. Therefore the sensitivity was 79%, and the positive predictive accuracy was 91%. Transthoracic two-dimensional echocardiography is a reasonable screening technique for diagnosis of aortic dissection.
通过对67例患者进行回顾性分析，评估经胸二维超声心动图在主动脉夹层患者中的应用价值：31例Ⅰ型DeBakey主动脉夹层患者，21例Ⅱ型患者，10例Ⅲ型患者，以及5例假阳性诊断患者。二维超声心动图正确识别出49例主动脉夹层患者；13例为假阴性诊断。因此，敏感性为79%，阳性预测准确性为91%。经胸二维超声心动图是诊断主动脉夹层的一种合理筛查技术。
