Characteristics of the microcirculation and blood rheology in arterial and venous forms of mesenteric vascular occlusion

The functional properties of microcirculation and rheology of blood were studied in dogs subjected to arterial and venous occlusion of mesenteric vessels (cranial mesenteric artery and cranial mesenteric vein). It was found that a local alterations of microvascular bed of intestinal wall are quite different in case of arterial or venous occlusion. The degree of hemorheological and microvascular deviations is higher in case of acute venous thrombosis than during the acute occlusion of cranial mesenteric artery.
