Abstract
The authors studied the predictive value of detailed fetal sonographic parameters on outcomes for 55 patients with prenatally diagnosed congenital diaphragmatic hernia managed at an extracorporeal membrane oxygenation center. Their sonographic assessment included gestational age at time of diagnosis, polyhydramnios (largest amniotic fluid pocket diameter), presence of liver and/or stomach herniation and abdominal circumference at the level of the umbilical cord. This series is from the original Fetal Treatment Center in San Francisco led by Michael Harrison, though Roy Filly clearly deserves much credit as the actual ultrasonologist doing the scans. They sought to establish a practical prognostic score for evaluation of the antenatally detected congenital diaphragmatic hernia.
