ABSTRACT
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-vesseltrachea 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.
