完全性大动脉转位的多普勒超声心动图诊断

目的:分析多普勒超声心动图诊断完全性大动脉转位(C-TGA)的准确性,提高超声心动图的首次检出率。方法:经外科手术证实为C-TGA的118例患者为研究对象,回顾性分析其超声心动图表现。结果:118例患者中,心房正位,心室右袢大动脉右转位112例,占94.9%;心房反位,心室左袢大动脉左转位6例,占5.1%。常见的合并畸形有房间隔缺损/卵圆孔未闭85例(72.0%)、动脉导管未闭68例(57.6%)、室间隔缺损35例(29.7%)、肺动脉狭窄29例(24.6%)、不典型冠状动脉13例(11.0%)。超声诊断正确者113例,占95.8%;误诊5例,占4.2%。在合并畸形中,误诊、漏诊不典型冠状动脉7例(53.8%)、动脉导管未闭2例(2.9%)。结论:多普勒超声心动图技术可以比较准确地诊断完全性大动脉转位。

Doppler echocardiographic diagnosis of complete transposition of great artery

Objective:To analyze the accuracy of the diagnosis of complete transposition of great artery(C-TGA) by Doppler echocardiography and improve the initial echocardiographic diagnosis.Methods:We retrospectively reviewed echocardiographic diagnosis of 118 children with C-TGA underwent surgical operation.Results:Of 118 children with C-TGA,d-transposition of the great arteries insitus solitus 112 cases(94.9%),l-transposition of the great arteries insitus inversus 6 cases(5.1%).85 cases(72.0%) were complicated by atrial septum defect or patent oval forammen,68 cases(57.6%) complicated by patent ductus arteriosus,35 cases(29.7%) complicated by ventricular septum defect,29 by atypical cases(24.6%) complicated by pulmonary stenosis,and 13 cases(11.0%) complicated atypical coronary artery.113 cases(95.8%) were diagnosed correctly,5 cases(4.2%) was misdiagnosed.7 cases(53.8%) with atypical coronary artery anatomy and 2 cases(2.9%) with patent ductus arteriosus were missed.Conclusion:C-TGA could be accurately diagnosed with precision by Doppler echocardiography.
