Successful treatment of bronchial anastomotic stenosis with modified Dumon Y-stent insertion in lung transplantation: report of a case.

Bronchial complications owing to airway anastomosis still remain a cause of morbidity and mortality following lung transplantation, and bronchial stenosis is the most common manifestation. Current treatment strategies include endoscopic balloon dilation, laser ablation, and stent insertion. Although a variety of stent types are currently available, it is unclear as to which type of prosthesis is most suitable for post-transplant bronchial complications with regard to the primary effects and long-term outcomes. We herein discuss a case of stenosis of the right bronchial anastomosis in a patient who underwent right single lung transplantation for idiopathic pulmonary fibrosis. This complication was successfully treated with the placement of a modified Dumon Y-stent. The stent was removed 2 months after insertion, and the patient has subsequently maintained an adequate airway caliber. Computed tomography, especially the sagittal section through the chest, is useful for detecting bronchial stenosis and monitoring the healing of this condition.
