title: [Blood circulation in the lungs during prolonged occlusion of the principal branches of the pulmonary artery and following restoration of their patency in experimental conditions].
abstract: The results of experiments on 36 dogs showed that in a lung with a ligated pulmonary artery the vascular network is maintained and the circulation of blood occurs through the bronchial arteries and their anastomoses with the pulmonary artery. The blood flow and total vascular bed increase in a functioning lung and the pulmo-arterial resistance diminishes. Desobliteration of the pulmonary artery leads to restoration of the main blood flow in it and the gas-exchange function of the lung which had been operated on, and to normalization of hemodynamics in the contralateral functioning lung.
