Material and methods. 3 sliding tracheoplasties under cardiopulmonary bypass were performed between March and May 2011. All patients had congenital extensive tracheal stenosis and concomitant cardiac and/or great vessel pathology. All three patients underwent sliding tracheoplasty according to Tsang V. and Goldstraw P. techniques combined with correction of congenital heart defect or great vessels. Results. Complications in early postoperative period was noted in 1 patient: he had evident growth of granulation tissue in anastomotic area which required a course of laser photocoagulation and prolonged intubation. Control study showed that tracheal lumen in 7 months was more than 5 mm without areas of evident deformation. Mean duration of stay in intensive care unit was 24 days, and length of mechanical ventilation was 16 days. 1 patient from experimental group died. Conclusion. Sliding tracheoplasty can be considered as the method of choice in congenital extensive tracheal stenoses in children. Cardiopulmonary bypass is indicated in case of concomitant heart and great vessel diseases and according to authors it facilitates the access to trachea. To the present day authors determined the staging of surgical intervention and features of management in postoperative period in children with extensive tracheal stenoses which allow to predict positive results of treating this pathology.
