[Ischemic and postischemic disorders of pulmonary microcirculation].
The time course of pulmonary microcirculatory disorders was studied in dogs with experimental pulmonary ischemia depending on its duration. With ischemia the lung manifested the growth of deaeration, intravascular aggregation of formed elements of the blood intensified, giving rise to the areas within distinct contours of the vascular pattern. After the recovery of circulation and ventilation in the ischemized lung, intravascular changes were manifested by the delayed corpuscular blood flow, aggregation of formed elements and blood stasis in the microvessels. Meanwhile vascular changes were manifested by variation of the shape and capacity of the microcirculatory bed, as well as by pathologically high microvascular permeability. The intensity of post-ischemic disorders was determined by ischemia duration.
