Extensive posterior-lateral tracheal laceration complicating percutaneous dilational tracheostomy

Background. An extensive posterior-lateral longitudinal tracheal laceration is an uncommon but serious complication of percutaneous dilational tracheostomy (PDT). We report the successful management of three ventilator-dependant patients whose percutaneous tracheostomy was complicated by an extensive longitudinal posterior-lateral tracheal laceration requiring operative repair. Methods. A retrospective review of 134 cases of PDT with concurrent bronchoscopy was performed between April 1997 and July 1999 and compared with a review of 124 cases of open tracheostomy. Tracheal lacerations were primarily repaired and augmented with intercostal muscle pedicle buttress. Results. Three cases of an extensive posterior-lateral longitudinal tracheal laceration that required operative repair were reported in the PDT group. None were reported in the open tracheostomy group. The 3 patients were managed with an adult high-frequency oscillating ventilator or pressure control ventilation during the postoperative period to limit barotrauma, and all healed without evidence of tracheal leak or stenosis. Conclusions. The increasing popularity of PDT, particularly among nonsurgical disciplines, may generate an increasing number of complications requiring operative attention. Thoracic surgeons need to be cognizant of the pitfalls of PDT technique and be prepared to manage these difficult clinical scenarios.
