Persistent peripheral bronchopleural fistulas can be difficult to manage. Endoscopic plugging of involved bronchi has been accomplished in a number of ways. We have devised a method of permanently blocking small peripheral airways using Gianturco vascular occlusion coils placed endobronchially by modified angiographic techniques. This procedure has been applied in 5 cases of complicated parenchymal air leaks. Complete or substantial partial control was achieved in all cases. There were no complications.
