Congenital trachea stenosis due to complete trachea ring was a life threatening, especially with symptomatic small infants. This study was conducted to evaluate the short-term results of sliding tracheoplasty for complete trachea ring in Children Heart Center-National Children’s Hospital, Hanoi, Vietnam. Methods: From September 2016 to March 2021, all patients operated using slide tracheoplasty technique, withdiagnosed of congenital trachea stenosis due to complete trachea ring, were retrospective study. Results: There were 75 patients collected during study period.The median age of the study group was 7 months (range, 7days old-5.5 years old). The median length of the stenotic trachea was 4.5cm (range, 2-6cm). There were 5 early deaths (6.7%), and 2 late death (2.6%). 3 patients (4%) need reoperation during follow-up with mean follow-up time was 20.6 14.9months. There were 20 patients (26.7%) have simple congenital trachea stenosis, and the remaining patients were associated with intracardiac lesions (pulmonary artery sling, double outlet of the right ventricle, tetralogy of Fallot, transposition of the great arteries…). There were 19 patients with severe airway collapse required ventilator support before operation, with 6 patients needing cardiopulmonary resuscitation and emergence cardiopulmonary bypass when the patients were transferred to the operating theatre. The anatomic of trachea were: 61 patients are normal (81.3%), 11 patients are bronchus suis(14.7%), and 3 patients (4%) are single lung. Conclusion: The early results of slide tracheoplasty for children with complete trachea ring in Children Heart Center, Hanoi is excellent. Long-term follow-up is essential.
