[Changes of pulmonary and bronchial vascularisation in disseminated lung diseases (author's transl)].
Pulmonary and bronchial artery angiographic pictures were evaluated in 14 patients with pulmonary disseminations. Diffuse fibrosing alveolitis was present in 4 patients, in 4 other patients secondary pulmonary fibrosis and in 6 patients pulmonary sarcoidosis. Most changes of pulmonary vascularisation were found in the lobular and terminal branches of the pulmonary artery. They consisted in their narrowing and even occlusion. Different degrees of the reduction of pulmonary perfusion could be observed. The most morbid alterations were in fibrosing alveolitis. They were less pronounced in cases of secondary fibrosis, showing a localized character, and in sarcoidosis in which the upper pulmonary parts were involved. Bronchial artery vascularisation was showing hypervascularisation of various degrees. Increased and dilated vessels strongly winding and even reticularly arranged could be regularly found. These alterations were very pronounced in patients with sarcoidosis. After transgressing of the pathological process to the state of fibrosis the vessels were showing a striped course presenting a greater number of broncho-pulmonary anastomoses.
