The @entity338 includes @entity849 , and @entity338 . The pulmonary arteries are aneurysmal and usually compress the tracheobronchial tree. These features are associated with a @entity1757 and @entity8158 . Nineteen @entity1 aged 5 days to 11 years were treated between 1976 and 1983. Nine were younger than 1 year. Intractable respiratory symptoms and @entity712 were the main features in the @entity1 group; five required preoperative assisted ventilation. Older @entity1 had decreased exercise tolerance and repeated @entity1729 . Several surgical techniques were used in this series. The best results were achieved when the size of the main, right, and left pulmonary arteries was reduced by extensive anterior resection; the @entity1757 was closed; and an aortic homograft was interposed between the right ventricle and the pulmonary artery. Four @entity1 and four @entity1 treated in this way survived the operation. Five of the nine operated @entity1 died (56%); all older @entity1 survived the operation. At follow-up, six @entity1 were asymptomatic and one was in New York Heart Association Class II. All four @entity1 were progressing satisfactorily although all had some @entity358 . Closure of the @entity1757 , reduction of the size of the pulmonary arteries, and insertion of an aortic homograft was the optimal treatment in our series.
