Three kinds of resection of the tracheal bifurcation were practically used in combination with extended pneumonectomy in patients with lung carcinoma. They were: graft-wedge shaped resection, wedge-shaped resection with ablation of the carina, resection of the tracheobronchial angle. The application of II-shaped sutures after resection of the trachea and bronchi in 32 patients has revealed a number of their advantages over single interrupted sutures. The outcomes of such interventions are favourable if the operations were performed in non-infected tissues.
