Mitomycin C for control of recurrent bronchial stenosis - A case report

A 27-year-old patient with cystic fibrosis underwent a bilateral lung transplantation despite the presence of multiresistant Burkholderia cepacia. Postoperatively, the patient presented with bilateral bronchial necrosis. During the 14th week, his FEV1 dropped to 2.5 L from a baseline level of 3.4 L. A subtotal occlusion of the right mainstem bronchus below the suture was noted. Using argon electrocoagulation, the right upper lobe bronchus, the intermediate bronchus, and the right middle lobe bronchus were reopened. During the period between weeks 20 and 42 post-transplantation, a recurrent stenosis required eight endoscopic interventions combining dilatation and stenting. During the 42nd week, dilatation followed by mitomycin C application stabilized the right lung function. Thus case report is the first to describe the effectiveness of the local application of mitomycin C to stop recurring extensive bronchial stenosis following bronchial necrosis secondary to lung transplantation.
