This paper describes the results of anatomohistological examination of a typical arteriovenous shunt (AVS) harvested from the leg. It has been revealed that the shunt structure is in full agreement with its functional aims. This manifests by the well-developed muscular layer (comparable with the muscular layer of the great artery) and developed adventitia in which the collagen fibers determine the rigidity and resistance to the intravascular blood pressure. The authors substantiate the hypothesis of the role played by the AVS in regulation of peripheral circulation as its indispensable constituent.

KEY WORDS: arteriovenous shunt, morphology, hemodynamics.
