[Morphology of the microcirculatory bed of the lungs and visceral pleura in liver cirrhosis].

Morphological examinations of the microcirculatory bed of the lungs and pulmonary pleura in 30 fatal cases of cirrhosis of the liver revealed generalized involvement of the blood and lymph vessels. Most significant changes were found in venular and lymphomicrocirculatory parts of the pulmonary pleura as a manifestation of compensatory-adaptative processes directed at retention of the hemodynamic homeostasis of the pulmonary circulation. In the author's opinion, the most important factors causing reactions of the microcirculatory bed of the pulmonary pleura include venous hypervolemia of the pulmonary circulation followed by hypoxia. It is suggested that changes in the vessels of the microcirculatory bed of the lungs and pulmonary pleura in patients with cirrhosis of the liver are an important part of the compensatory-adaptative mechanisms; their disorders cause the development of the right ventricle insufficiency.
