1226: Ultrasound Diagnosis of Fetal Aortic Arch Anomalies

To analyze the methods of prenatal sonographic diagnosis of all kinds of aortic arch anomalies and to improve prenatal sonographic detection rate of aortic arch anomalies. Methods: 73 fetuses with congenital aortic arch anomalies were stydied.The results from prenatal ultrasound examination,postnatal examination were compared. Results 73 cases were with congenital aortic arch anomalies, 33 cases with malposition of aortic arch ,9 cases with normal left aortic arch with aberrant left subclavian artery, 5 cases with interruption of aortic arch,26 cases with coarctation of aortic arch. The accuracy rate of prenatal sonographic diagnosis was 87.7%. Conclusions Aortic arch anomalies have typical sonographic image. If we grasp typical sonographic images,we could make accurate diagnosis.
