Abstract:
The article describes a non-standard surgical approach to the treatment of a tumor with a predominant lesion of the membranous wall of the trachea. The method of circular resection with wide excision of the membranous wall of the trachea and replacement of tissue deficiency with an autopericardial flap is used. This approach, in comparison with the standard technique, allowed to significantly reduce the tension of the anastomosis sutures, ensured a smooth postoperative period and relapse-free survival for more than 7 years in the context of combined treatment of adenoid cystic tracheal cancer.
