[Microsurgical sutures of the trachea and bronchi (experimental study)].

A method for the formation of tracheal and bronchial anastomoses with a two-row suture by means of microsurgical techniques was elaborated in experiments on 52 mongrel dogs. In the control series the bronchial anastomosis was created with interrupted sutures passed through all the coats of the bronchial wall. Morphological study of the reparative processes in the tracheal and bronchial anastomoses showed that healing of the anastomosis formed by means of microsurgical techniques occurred sooner and with a lesser inflammatory reaction than healing of the communication in the control series. This is explained by the fact that the microsurgical suture of the tracheal and bronchial mucosa ensures adequate approximation of the margins of the anastomosis and reliable air-tightness and promotes healing by first intention.
