Clinical/epidemiological analysis of congenital anomalies associated with diaphragmatic hernia.

Several studies have been published on congenital diaphragmatic hernia (CDH), either as an isolated defect or as part of a multiple congenital anomaly (MCA) pattern. Here we present an epidemiological study designed to measure the association between CDH and a group of 17 selected congenital anomalies in an attempt to identify groups of specific defect patterns. This analysis was done using the data from the Spanish Collaborative Study of Congenital Malformations (ECEMC).
