[Significance of the arrest of pulmonary circulation in the genesis of postperfusion pulmonary complications in open heart surgery].
The purpose of the work is to elucidate the importance of pulmonary circulation arrest during extracorporeal circulation in the development of microcirculatory disorders in the pulmonary tissue. Experiments showed that temporary arrest of pulmonary circulation under conditions of extracorporeal circulation is attended by the development of ischemia of the respiratory pulmonary tissue. The systemic blood flow in the arterio-arterial anastomoses between the pulmonary and bronchial arteries is incapable of providing the pulmonary tissue with blood. Ischemia of the parenchyma leads to disorders in the microvessels of the organ, the manifestation of which in the ischemic and postischemic, periods is determined by the duration of the pathologic effect. The data gained indicate the importance of developing methods for the prevention and treatment of ischemic and postischemic pulmonary microcirculatory disorders and determining the safe terms of pulmonary artery ischemia.
