【摘要】：目的探讨胎儿完全型肺静脉异位引流(TAPVC)产前诊断线索及超声心动图特征。方法回顾性分析于我院经超声诊断并经尸体检查或出生后超声心动图证实的14胎TAPVC胎儿的二维及多普勒图像的特征。结果产前诊断12胎TAPVC,其中心上型9胎,心内型2胎,心下型1胎。TAPVC的产前诊断线索及超声心动图特征:二维超声四腔心切面未显示肺静脉角,左心房后壁光滑;左心房后壁与降主动脉间距离增大;可见共同肺静脉腔和垂直静脉。产前超声心动图漏诊2胎,经出生后超声心动图证实均为心内型TAPVC。14胎TAPVC中,4胎伴肺静脉引流途径梗阻。结论胎儿超声心动图可诊断TAPVC并准确分型;脉冲和彩色多普勒超声可显示肺静脉回流途径梗阻。
[Abstract]:Objective to investigate the prenatal diagnostic clues and echocardiographic features of fetal complete anomalous pulmonary venous drainage (TAPVC). Methods retrospective analysis was made on 14 TAPVC fetuses confirmed by echocardiography in our hospital and confirmed by cadavers or postnatal echocardiography. Results 12 cases of TAPVC were diagnosed by prenatal diagnosis, including 9 cases of supracardiac type. Antepartum diagnostic cues and echocardiographic features of intracardiac type 2 and subcardiac type 1 路TAPVC: the angle of pulmonary vein was not shown on the four-chamber view of two-dimensional echocardiography, the posterior wall of left atrium was smooth, and the distance between the posterior wall of left atrium and descending aorta was increased. Common pulmonary vena cava and vertical vein were found. Prenatal echocardiography missed the diagnosis of 2 fetuses. Postnatal echocardiography was proved to be obstruction of 4 cases of intracardiac TAPVC.14 fetal TAPVC with pulmonary venous drainage. Conclusion Fetal echocardiography can diagnose and type TAPVC accurately, pulse and color Doppler ultrasound can show obstruction of pulmonary venous drainage pathway.
