The applications of bronchial pulmonary artery angioplasty in elderly patients with central lung cancer

Abstract

Objective To study the effectiveness of bronchial pulmonary artery angioplasty in elderly patients with central lung.Methods 78 elderly patients with central lung were randomly divided into two groups,the control group（n=39） and the observation group（n=39）.The patients in the control group were operated through pneumonectomy,while the observation group was operated through bronchial pulmonary artery angioplasty.1,3,5-year survival rates were compared.Incidence of postoperative complications were counted.The changes in pulmonary func-tion after 3 months were determined.Results The survival rates in the control group were 66.7%（26/39）,46.2%（18/39）,30.8%（12/39） and 79.5%（31/39）,56.4%（22/39）,38.5%（15/39） in the observation group.The survival rates of the observation group were significantly higher （χ^2=6.17,7.06,4.82,all P〈0.05）.The control group had 11 cases of complications after surgery,the rate was 28.2%.The observation group had 4 cases of postoper-ative complication,the rate was 10.1%.The incidence of complications in the observation group was significantly less than that of the control group （χ^2=6.32,P〈0.05）.There was no significant difference （t=0.72,0.11,0.39,all P〉0.05） between the two groups before treatment about FVC,PEF and FEV1.After treatment,FEV1,FVC,PEF were significantly improved （t=5.92,7.92,4.11,7.01,5.99,6.82,all P〈0.01）.The degree of improvement in the observation group was higher than that of the control group （t=2.84,2.77,3.28,all P〈0.05）.Conclusion Bron-chial pulmonary artery angioplasty has significantly fewer complications,can be further improved lung function in eld-erly patients with central lung cancer.
