The management of congenital tracheal stenosis

Abstract

This paper reviews current concepts and results in the management of congenital tracheal stenosis (CTS). Diagnostic options are considered and the requirements for successful management defined. Chief amongst these is a multi-disciplinary approach with individualised patient management. Severe long-segment CTS represents the biggest challenge to clinicians and the worst problems for affected families. Near-death episodes are frequent in affected infants and some cannot be ventilated and require ECMO. Associated cardiovascular anomalies are frequent. Patients require immediate resuscitation and transfer to a specialist unit. After careful assessment, accurate diagnosis and discussion, primary resection and end-to-end repair with a slide technique should always be the first option, with concomitant repair of associated cardiac anomalies. If this is impossible because of the severity of the lesion, some form of patch tracheoplasty will be indicated. Cardiopulmonary bypass is often required. Patches include pericardium, autograft trachea, carotid artery, cartilage, and allograft trachea. Mortality ranges from 0 to 30% in the literature, which largely comprises single-centre long-term experience. Recurrence is common and can be managed by stenting and tracheal homograft implantation. Long-term quality of life of survivors is little reported but seems good. Physiological data are lacking. To improve results, we suggest a treatment algorithm to rationalise care.
