[Congenital diaphragmatic hernias].

Based on their personal experience the authors affirm that if treated early congenital diaphragmatic hernia may be resolved provided no congenital anomalies are present. Pulmonary hypoplasia is secondary to the presence of viscera in the thorax, but excellent results can be obtained if early surgery is performed and provided negative-pressure thoracic drainage and correct anesthesia are ensured. Mortality is due to associated visceral malformations.
