Surgical treatment of tracheal stenosis in children / 中华胸心血管外科杂志

ABSTRACT

Objective:To investigate the common types, surgical treatment and effects of tracheal stenosis in children.Methods:A total of 23 children with tracheal stenosis in our hospital from December 2017 to August 2020 were retrospectively reviewed, including 14 males and 9 females. The mean age at operation was(8.9±5.8)months(range: 2-3 months) and the mean weight was(6.4±2.3)kg(range: 4.2-10.5 kg). The common types of tracheal stenosis were complete tracheal ring in 9 children, tracheomalacia in 10 and subglottic membranous annular hyperplasia in 4. The type of congenital heart diseases included 10 patients of pulmonary artery sling, 1 of tetralogy of Fallot, 5 of ventricular septal defect, 1 of pulmonary atresia, and 1 of right aortic arch with aberrant left subclavian artery. Slide tracheoplasty was performed in 9 patients, external splint in 8, endotracheal stent in 2 and tracheal dilation in 4. All children were followed up after 1, 3, 6, and 12 months of operation with CT and bronchoscopy.Results:There was 1 death in all 23 patients and the mortality was 4.3%, which died of granulation tissue hyperplasia after slide tracheoplasty. Reoperation was performed in 1 patient with endotracheal stent. All patients were followed for 1 to 24 months. Clinical symptoms of tracheal stenosis disappeared and the results of CT and bronchoscopy were satisfied.Conclusion:Slide tracheoplasty is the effective surgical method for complete trachea ring. 3D printing bioresorbable external splint is a promising method for the treatment of tracheomalacia.
