[Pulmonary hemodynamics in acute and chronic inflammatory lung diseases in children].

The author carried out a study of pulmonary hemodynamics in 155 patients aged 1 month to 15 yrs. old with acute and chronic pulmonary inflammatory diseases by radionuclide diagnostic, angiographic and other methods. It was established that angiological mechanisms of the pathogenesis of acute suppurative-destructive pneumonia were based on the reduction of the microcirculatory network of the pulmonary vessels with regional redistribution of the blood flow. Lesser circulatory rearrangement in chronic nonspecific pulmonary inflammatory diseases was characterized by regional hypoperfusion in the affected zone, a decrease in oxygen saturation of the blood, reduced blood flow volumes, and regional arterial pulmonary hypertension.
