[Experimental validation of the method of autografts creation for arteries]

Experimental studies on rats have demonstrated possibility of connective-tissue grafts formation on polyvinylchloride base introduced subcutaneously. Dynamics of autograft formation is characterized by gradual thinning of wall, regulation of collagen fibers, decreased number of cells with fibrocytes predominance. Autografts in carotid position retain its patency during 3 months, and endotheliocytes appear on their internal surface.
