Left mainstem bronchial laceration with perforation to right pleural cavity as complication after dynamic stent insertion.

The development of science at the end of the 20(th) century introduced new surgical miniinvasive techniques. Endoscopic insertion of an internal stent is an alternative to other, older techniques in the treatment of tracheobronchial stenosis. Complications are serious and require immediate intervention. We report a case of a 53-year-old patient with left mainstem bronchus perforation during insertion of a dynamic stent. The clinical presentation was characterised by right tension pneumothorax. The dynamic stent in the right pleural cavity on computed tomography scan was observed. Right postero-lateral thoracotomy, stent evacuation and tracheal sutures were performed. Tracheal granulation was treated with argon plasma coagulation. Early diagnosis and treatment offered good current effects.
