心血管数字造影和超声心动图在大动脉错位诊断中的作用

Effects of cardiovascular digital imaging and echocardiography in the diagnosis of transposition of the great arteries

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。材料和方法:采用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等检查技术对34例大动脉错位患者进行了对比研究,其中14例有手术结果对照。结果:心血管数字造影与手术结果符合率为85.7%(12/14);心脏超声与手术结果符合率为78.6%(11/14)。两者均能清楚显示心室与大动脉连接部畸形;心脏超声对心内结构的显示具有优势,心血管数字造影对大血管及其他心外结构的异常的评价更加准确。结论:心血管数字造影与心脏超声相结合,能提高大动脉错位诊断的准确率。

Objective:To evaluate the value of cardiovascular digital imaging and echocardiography in the diagnosis of transposition of the great arteries.Materials and Methods:Thirty-four cases of transposition of the great arteries were studied by the techniques of cardiovascular digital imaging,two-dimensional echocardiography and color Doppler flow imaging,14 cases of them underwent surgery.A comparison was made between the data obtained and surgical findings.Results:The rate of coincidence of digital imaging in diagnosing transposition of the great arteries with operation was 85 7%(12/14) in comparison with 78 6%(11/14) of coincidence with operation in echocardiography.Both of them can clearly show the abnormalities of ventricles and the great arteries.Echocardiography has an advantage in displaying the intra-cardiac structures,but cardiovascular digital imaging was more accurate than echocardiography in evaluating abnormalities of the great vessels and other extra-cardiac structures.Conclusion:Combining cardiovascular digital imaging with echocardiography can greatly improve the rate of diagnostic accuracy for transposition of the great arteries.
