Surgical management of congenital tracheal stenosis associated with tracheal bronchus and congenital heart disease.

Abstract

Congenital tracheal stenosis (CTS) is variable in patients with tracheal bronchus and congenital heart disease (CHD). Tracheoplasty remains a high-risk surgical treatment. From January 2007 to December 2014, 24 CTS patients (10 males and 14 females; age 20.6 ± 13.6 months) with tracheal bronchus and CHD underwent one-stage surgical correction. Clinical features of all patients included dyspnoea, or recurrent pulmonary infections. There was long-segment CTS in 13 cases (54%), and 4 cases were associated with a bridging bronchus. Less than 50% of normal tracheal size was identified in 21 cases. Complete tracheal or bronchial rings were identified in all cases. Operative techniques included: tracheal end-to-end anastomosis in 11 cases and slide tracheoplasty in 13 cases, which included 11 cases of right upper lobe bronchus (RULB) opposite side-slide tracheoplasty. There were 2 operative deaths, due to postoperative tracheomalacia or residual main bronchial stenosis. The duration of postoperative hospital stay was 7-59 days, with an average of 19 days. Follow-up was completed in 19 cases. The follow-up duration was from 1 month to 7 years. Tracheal granulation occurred in 1 case. Clinical symptoms were significantly improved in the remaining patients. Tracheal bronchi have special anatomical features. The techniques of tracheal end-to-end anastomosis or side-slide tracheoplasty can be used to correct tracheal stenosis with satisfactory outcomes.
