[The pathological changes in pulmonary vessels complicated by cirrhosis with anatomicopathological analysis of 30 cases].

The pulmonary sections HE stained in 30 autopsy cases of cirrhosis were randomly reexamined. The distribution and degeneration of pulmonary arterioles and venules which were at alveolar level and the diameter of capillaries were observed; 10 autopsy cases of other diseases were examined as control. The results showed tricuspid orifices were dilated in 20% of autopsies; Both lungs were heavier than those in the control group, pulmonary congestion were in 100% of autopsied lungs. Pulmonary artery degeneration occurred in 16.6%, the number of pulmonary arterioles increased in 73.0%, the hypertrophic dilatation and increasing number of pulmonary arterioles in 33.3%; local spider in pulmonary pleura in 20%. We conclude that above findings will be helpful to the indirect diagnosis of intra-pulmonary shunt and pulmonary hypertension.
