Objective To investigate the effectiveness and the surgical experience of bronchoplasty and pulmonary artery reconstruction in the treatment of lung cancer of the left pulmonary artery affected. Methods From January, 1990 to December, 2004, 16 patients with lung cancer of the left pulmonary artery affected underwent bronchoplasty and pulmonary artery reconstruction. According to TNM classification, 16 patients were in stage ⅢA. The surgical procedures included sleeve resection of bronchus in 16 cases, sleeve resection of pulmonary artery in 11 and wedge resection of pulmonary artery in 5. Results The overall 1, 3 and 5-year survival rates were 75.0 %, 45.5 %, and 33.3 % respectively. Conclusion The results suggest that brenchoplasty and pulmonary artery reconstruction for the patients with lung cancer of pulmonary artery affected is an effective surgical technique. This method extends the surgery indications to patients with poor lung function and senility by reducing the ratio of pneumonectomy and improving postoperative quality of life. Therefore, it is clinically valuable.
