[Microcirculatory disorders caused by gunshot wounds of the small intestine (experimental study)]

The mirocirculatory dynamics in intestinal wall at different distances from the wound canal was established in experimental dogs using the stimulation of jejunal high-energetic gunshot injury. The radial spectrum of microcirculatory changes is characterized by the following parameters: the decreased arterio- and arteriole spasm, the increased insufficiency of venous outflow, the capillary net "thickening" and the increased load on lymph drainage system. Temporal dynamics is manifested by insignificant resolution of arterio- and arteriole spasm with remained microcirculatory disorders. Together with rather stable microvascular morphometric parameters there were the following disorders: the irregular spasm and sludge in capillaries, the endotheliocyte swelling, the increased venous congestion. The microcirculatory state determines both the degree of morphologic changes in the zone of gunshot injury of intestinal wall and the intensity of compensatory-and-adoptive processes.
