Popis: In congenital diaphragmatic hernia (CDH), there is pulmonary hypoplasia (PH) and also pulmonary vascular and bronchial abnormalities. Few studies have investigated bronchial maldevelopment in CDH. We evaluated bronchial area (BA) by bronchography in a fetal lamb DH model to develop a measure of PH. We created DH in fetal lambs at 75 days gestation, delivering by cesarean section and killing them at term (DH, n = 12). Normal term fetuses provided controls (C, n = 5). We measured total lung volume (TLV) and performed barium bronchography. Using image analysis, BA, total lung area (TLA) and bronchial area/lung area ratio (B/L ratio) were calculated. Student’s T test (p
