目的探讨胎儿主肺动脉间隔缺损(APSD)的超声心动图特征及产前诊断的价值。方法回顾性分析我院5例胎儿APSD的二维及彩色多普勒图像,总结其诊断要点。结果 5例APSD均可探及升主动脉与主肺动脉之间回声中断,CDFI示双向低速血液分流。5例APSD胎儿中,2例单纯主肺动脉间隔缺损,2例合并主动脉弓离断,1例合并主动脉缩窄。结论胎儿超声心动图能够准确地诊断APSD。产前诊断APSD有利于产前咨询和出生后早期治疗。
Objective To investigate the echocardiographic features and prenatal diagnosis of fetal primary pulmonary septal defect (APSD). Methods A retrospective analysis of 5 cases of fetal APSD in our hospital two-dimensional and color Doppler images, summarizes the diagnostic points. Results All five cases of APSD were probed and the echogenicity between the ascending aorta and the main pulmonary artery was interrupted. CDFI showed bi-directional low-speed blood flow diversion. Of the 5 APSD fetuses, 2 had simple primary pulmonary septal defect, 2 had aortic arch disconnection, and 1 had narrowed aorta. Conclusion Fetal echocardiography can accurately diagnose APSD. Prenatal diagnosis of APSD is conducive to prenatal counseling and early postnatal treatment.
