大动脉错位心血管数字造影和超声诊断的对比研究

目的评价心血管数字造影和心脏超声在大动脉错位诊断中的作用.方法30例大动脉错位患者全部进行心血管数字造影和心脏二维超声心动图以及彩色多普勒血流图检查,其中11例39个畸形有手术结果对照.结果心血管数字造影与手术结果符合率为92.3%(36/39);心脏超声与手术结果符合率为84.6%(33/39).这两种技术均能清楚显示心脏、心脏与大血管连接部畸形;心脏超声对瓣膜病变敏感性高,心血管数字造影对大血管病变以及体肺侧枝循环的判断具有优势.结论心血管数字造影与心脏超声有机结合,能提高大动脉错位诊断的准确率.

Comparative Study of Cardiovascular Digital Imaging and Echocardiography in Diagnosis of Transposition of the Great Arteries

Objective To evaluate the value of cardiovascular digital imaging and echocardiography in diagnosis of transposition of the great arteries.Methods Thirty cases of transposition of the great arteries were examined with cardiovascular digital imaging technique,two-dimensional echocardiography and color Doppler.11 cases of them underwent surgery.A comparison was made between the data obtained and surgical findings.Results The rate of coincidence of digital imaging and echocardiography with operation in diagnosing transposition of the great arteries was 92.3%(36/39)and 84.6%(33/39) respectively.Both echocardiography and cardiovascular digital imaging techique could clearly show the abnormalities of the heart and great vessels.Echocardiography was sensitive to valvular pathological changes,though cardiovascular digital imaging was superior to echocardiography in demonstrating abnormalities of great arteries and systemic-pulmonary collateral circulations.Conclusion Combination of echocardiography with cardiovascular digital imaging technique can greatly improve the rate of diagnostic accuracy for transposition of the great arteries.
