目的探讨肺功能储备低下的老年中央型肺癌在肺动脉受肿瘤侵犯，患者又难以耐受全肺切除术时的手术方法。方法采用肺动脉楔形切除或袖状切除行肺动脉成形肺叶切除术对３６例此类病人进行手术治疗。结果术后出现肺部感染４例，哮喘发作２例，手术死亡１例，无与肺动脉成形直接相关的并发症发生。术后１年生存率８１．３％，３年生存率５２．６％，５年生存率２６．５％。结论肺动脉成形术可扩大肺癌手术适应证，降低全肺切除率，尤其适合心肺功能储备低下的老年患者，术后严密的监护治疗是手术成败的关键。
OBJECTIVE: To investigate the effects of low lung function reserve on lung cancer in patients with central lung cancer in the elderly, and it is difficult for the patients to tolerate surgical procedures for pneumonectomy. Methods Pulmonary arterial wedge resection or sleeve resection pulmonary lobectomy was performed on 36 patients. Results There were 4 cases of pulmonary infection, 2 cases of asthma attack, 1 case of surgical death, and no complications related to pulmonary artery formation. The 1-year survival rate was 81.3%, the 3-year survival rate was 52.6%, and the 5-year survival rate was 26.5%. Conclusions Pulmonary angioplasty can expand the indications of lung cancer surgery and reduce the rate of pneumonectomy. It is especially suitable for elderly patients with low cardiopulmonary reserve. Postoperative strict monitoring and treatment is the key to the success of surgery.
