[Possibility of restoration of the respiratory function of the lung after recanalization of the pulmonary artery after its long-term experimental occlusion].

The gas-exchange function, blood circulation and structure of the revascularized lung after a continuous (up to 3 months) occlusion of its pulmonary artery were studied in 36 dogs in experiment. The repair of the artery patency resulted in the reestablishment of blood flow, gas-exchange function of the lung, normalization of the structure and metabolic processes in its cells. The functional competence of the revascularized lung was estimated by the ability of the animal to survive after removal of 3 lobes of the intact right lung, with the upper lobe only being left.
