A 76-year-old patient had an elective percutaneous dilatational tracheostomy (PDT) under endoscopic control in the intensive care unit. Twelve days later when her general condition improved, two attempts at decannulation failed due to upper airway obstruction above the tracheostomy site.
Bronchoscopy showed herniation of the anterior tracheal wall above the tracheostomy tube occluding 80 per cent of the lumen. The herniated anterior segment was elevated and partially resected under endoscopic guidance. The patient made a full recovery and was decannulated on the first post-operative day. Pitfalls and possible complications of PDT are discussed.
