Abstract:
The authors describe a non-standard surgical approach to the treatment of tumor with predominant lesion of membranous tracheal wall. Circular resection with wide excision of membranous wall and replacement of tissue deficiency with autopericardial flap are used. This approach significantly reduced tension of anastomotic sutures, ensured smooth postoperative period and relapse-free survival over 7 years in context of combined treatment of adenoid cystic tracheal cancer.
