Abstract
The status of bronchial arterial collateral circulation and the pulmonary vasculature in 50 cases of pulmonary stenosis with ventricular septal defect and 26 cases of pulmonary stenosis with intact ventricular septum, ranging in age from 1 month to 32 years, were studied at necropsy. Occlusive changes in pulmonary vessels were present in cases over 15 years of age in whom bronchial collaterals were poorly developed. The importance of bronchial collaterals for the proper evolution of pulmonary vasculature in cases of severe pulmonary stenosis is stressed.Keywords
