P15.12: Prenatal diagnosis of severe combined immunodeficiency (SCID): ultrasonographic detection of the absence of cavum septi pellucidi may be predictive?

Abstract

Objective: 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 studied. 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.
