The Pulmonary Vasculature in Complete Transposition of the Great Vessels, Judged from Lung Biopsies

摘要: Specimens of the lung taken for biopsy at operation on 80 patients with complete transposition great vessels were histologically studied in correlation clinical and hemodynamic data these cases. In a group 31 cases intact ventricular septum patent foramen ovale, media pulmonary arteries was generally thinner than normal, to lesser extent that veins also, while lumina wide. This especially observed which hematocrit high. Possibly, this phenomenon is based dilatation related increased total blood volume. Intimal fibrosis, when observed, suggestive organized thrombi. 28 septal defect equal pressures left right ventricles, there marked medial hypertrophy concentric intimal proliferation arteries. pulmonic stenosis, other hand, pulmon...
