a Covering the right main bronchus with TPFF after right VATS pneumonectomy. Asterisks indicate dissected and prepared TPFF. The arrow indicates the stump of the right main bronchus. AV Azygos vein. b U-sutures passed through the peribronchial tissue and flap are seen. In order not to create extra tension on the stump, it would be more appropriate to pass the sutures through the peribronchial tissues instead of the bronchial cartilage. c Image of the thoracic cavity after completion of TPFF coverage
