Congenital diaphragmatic hernia diagnosed prenatally by ultrasound.

Abstract

Seven infants born at our institution between July 1979 and June 1982 had congenital diaphragmatic hernia (CDH). Four cases of CDH were correctly identified by fetal ultrasonography. Diagnosis relied upon the demonstration of abdominal organs within the thorax. During this period, no false positive diagnoses of CDH were made. Significant associated sonographic features included polyhydramnios, mediastinal displacement, and distorted upper abdominal anatomy.
