Abstract: Objective To explore the value of three-vessel and trachea(3VT) view plus aortic arch coronal section in ultrasonic diagnosis and classification of fetal right aortic arch(RAA).Methods Echocardiography data and follow-up results of 44 fetuses with RAA were retrospectively analyzed.Sonographic features on 3VT view and aortic arch coronal section were summarized.Results Among 44 fetuses with RAA,27 cases(61.36%) were RAA with aberrant left subclavian artery(ALSA) and the left ductus arteriosus(LDA) connecting the ALSA and U-shaped vascular ring was formed;17 cases(38.64%) were mirror right aortic arch(MRAA).Among 17 cases with MRAA,3 cases were with LDA connecting the descending aorta(DAO) and U-shaped vascular ring was formed;1 case was with LDA connecting the left innominate artery(LINA),8 cases were with absent ductus arteriosus(ADA),5 case were with right ductus arteriosus(RDA),no vascular ring was formed.Parts of MRAA were combined with other complex intracardiac abnormalities.RAA-ALSA-LDA were rarely combined with intracardiac abnormalities.Conclusions 3VT view is simple and intuitive for diagnosing RAA.Aortic arch coronal section has great clinical value in determining the concrete type of RAA.
