Laryngotracheal stenosis: a serious complication of percutaneous tracheostomy.

Abstract

Tracheostomy in patients requiring prolonged artificial ventilation in intensive care is increasingly being performed by a percutaneous dilatational technique, in preference to the standard surgical method. Since its introduction numerous series have reported favourably on its general safety in the short-term, but there have been few reports of longer term follow-up of patients. We present four cases of laryngotracheal stenosis, a previously unreported complication associated with the technique, and discuss the relevance of these to the future practice of percutaneous tracheostomy.
