title: [Morphological evaluation of the viability of silicon-lavsan tracheal prostheses].
abstract: Time course of the healing process in the tracheal wall during silicon-lavsan tracheal grafting was investigated in experiments on 108 dogs with a new model of tracheal prosthesis. The formation of granulation tissue was noted as a result of postoperative inflammatory reaction in the prosthetic area. The tracheal epithelial layer adjacent to the anastomoses was hypertrophic and acquired the features of squamous epithelium. Later, after the implantation the prosthesis was surrounded by a thick fibrous capsula. In anastomoses, at tracheal tissue--implant border there was a poorly expressed inflammatory reaction, which had a local character and was compatible with 3 and more years of life in most experimental animals.
