Bochdalek Hernia
Pronunciation: BAWK-dah-lek
Posterolateral congenital diaphragmatic hernia, the most common type of CDH, typically presenting on the left side.
Full Definition
Bochdalek hernia is the most common type of congenital diaphragmatic hernia, accounting for approximately 85% of cases. It results from failure of closure of the pleuroperitoneal canal during embryonic development, creating a posterolateral defect in the diaphragm. The left side is affected in 85% of cases, and abdominal organs herniate into the thoracic cavity, potentially causing severe pulmonary hypoplasia and pulmonary hypertension. Surgical repair involves reduction of herniated organs and closure of the diaphragmatic defect, often requiring patch repair. The condition is associated with significant morbidity and mortality, particularly when diagnosed prenatally.
Usage
