Treatment of bronchus intermedius stenosis in lung transplantation with Montgomery T-tube stent. A novel technique

Abstract

Airway complications after lung transplant are relatively common although the rates vary according to the different studies. Pathogenesis is diverse but the principal mechanism is usually bronchus intermedius ischemia in the post-transplant period. One major complication is bronchial stenosis, with relatively frequent involvement of the bronchus intermedius in the case of right lung transplantation. Various treatments have been proposed for bronchus intermedius stenosis, such as endobronchial balloon dilation, laser, cryosurgery and bronchial stents. We present two cases of lung transplant recipients with bronchus intermedius stenosis treated with a Montgomery stent or T-stent, commonly used for tracheal stenosis, who showed positive clinical and functional response.
