| 目的 胎儿动脉导管（DA）异常的超声心动图检查及分析。方法 回顾性分析产前诊断DA异常的70胎资料。二维超声结合彩色多普勒扫查胎儿四腔心切面、左右心室流出道切面、三血管切面及三血管-气管切面等横断面，扫查腔静脉长轴切面、主动脉弓切面及动脉导管弓切面等矢状面。观察DA的走行及与其他大血管的空间位置关系。结果 胎儿DA异常主要由DA缺如、DA功能异常及DA形态异常3类。70胎DA异常中，9胎DA缺如，8胎DA早闭，11胎DA即将闭合，9胎DA逆行灌注血流，33胎DA走行纡曲伴扩张。结论 产前诊断胎儿DA缺如及DA功能性改变意义重大。三血管-气管切面及动脉导管弓切面结合CDFI扫查可明确诊断。 |

| Objective To analyze the abnormal fetal ductus arteriosus (DA) by echocardiography. Methods Seventy fetuses of abnormal DA diagnosed prenatally were retrospectively reviewed. Transverse scans combined with color Doppler were used to acquire four chamber view, left and right ventricular outflow tract views, three vessel view, and three-vessel-trachea view. In addition, sagittal scans with color Doppler were used to get vena cava long axis view, aortic arch view, and ductal arch view. The spatial relationship of the great arteries and trend of DA were observed. Results Abnormal fetal DA is mainly composed of DA absence, DA abnormal function and DA morphological abnormality. Among 70 cases of fetal DA, 9 cases were diagnosed with DA absence, 8 cases were DA atresia, 11 cases were DA completed closure nearly, 9 cases were shown with reverse DA blood perfusion, 33 cases were shown with DA curvature and dilatation. Conclusion Prenatal diagnosis of DA absence and DA abnormal function is of great significance. Three-vessel-trachea view and ductal arch view combined with CDFI can make a definitive diagnosis. |
