Reconstruction of the pulmonary artery in patients with lung cancer.

Between March 1990 and December 1992, we performed 17 resections and reconstructions of the pulmonary artery (PA) in patients with lung cancer. Three patients with intrapericardial infiltration of the PA underwent left pneumonectomy and PA angioplasty through a median sternotomy during cardiopulmonary bypass. The first patient survived in excellent general health for 25 months and then died of brain metastases; the second died of bronchopneumonia on postoperative day 24; and the third died of generalized tumor spread after 3 months. Fourteen patients had extrapericardial infiltration of the PA. They underwent sleeve upper lobectomy and PA reconstruction instead of pneumonectomy. In 6 patients we performed a sleeve resection of the PA, and in 8, the vessel was reconstructed using a patch of autologous pericardium. Two minor postoperative complications occurred. Three patients died after 14, 15, and 20 months; the remaining 11 are alive and well 5 to 31 months after operation. We conclude that PA reconstruction associated with sleeve lobectomy is an advantageous alternative to pneumonectomy in select patients with lung cancer. Intraoperative indications, surgical technique, and perioperative management are crucial to achieve good results. Reconstruction of the main PA during cardiopulmonary bypass in association with left pneumonectomy can be performed successfully. The long-term results need further evaluation.
