  • Title: [Microcirculatory disorders in acute ischemia of the small intestine and in the postischemic period].
    Author: Shinkarenko VS, Collantes JJ.
    Journal: Patol Fiziol Eksp Ter; 1989; (4):49-52. PubMed ID: 2594430.
    Abstract:
    Microcirculation in the small intestine of rats during ischemia (from 5 to 240 minutes) and in the period of reperfusion (from 60 minutes to 10 days) was studied by biomicroscopy. Ischemia was modelled by ligating the base of the intestinal loop. Sharp microhemodynamic disorders occurred during ischemia, compensatory mechanisms intensifying the blood flow were switched on, the microvascular channel, including vessels which previously did not function, were dilated. Mechanisms concerned with redistribution of fluid in the intra- and perivascular space were evidently the underlying factors of capillary dilatation. In the late-term periods of reperfusion ischemia leads to increase of the number of microvessels in the ischemic part of the organ.
