对 ５０例晚期中央型肺癌行支气管动脉灌注治疗，以提高病人生存期。材料与方法：采用Ｓｅｌｄｉｎｇｅｒ法，经股动脉插管对５０例经病理证实的晚期中央型肺癌行支管动脉灌注治疗，男４１例，女９例，５０例共灌注１５４次。结果：晚期中央型肺癌经支气管动脉灌注治疗后，多血管型有效率９４．７％，少血管型有效率３３．３％，生存期１年以上７８％，平均生存期１６个月。结论：支气管动脉灌注治疗晚期中央型肺癌总有效率８０％，多血管型疗效优于少血管型疗效，支气管动脉灌注治疗晚期中央型肺癌有较好的临床疗效，可做为晚期中央型肺癌的有效治疗方法。
Fifty patients with late-stage central lung cancer underwent bronchial arterial infusion to improve their survival. Materials and Methods: Using Seldinger method, 50 patients with pathologically confirmed advanced central lung cancer underwent bifurcation arterial infusion with male femoral artery catheterization. There were 41 males and 9 females, and 50 patients received 154 injections. Results: After the treatment of advanced central lung cancer with bronchial arterial infusion, the effective rate of multi-vessel type was 94.7%, the effective rate of small vessel type was 33.3%, the survival period was more than 1 year 78%, and the average survival time was 16 months. Conclusion: The total effective rate of bronchial arterial infusion in the treatment of late-stage central lung cancer is 80%. The efficacy of multi-vessel is better than that of less-vessel-type. The bronchial arterial infusion for the treatment of advanced central lung cancer has better clinical efficacy and can be used as advanced central lung cancer. Effective treatment methods.
