目的 应用数字图像系统，动态观察肺癌血液循环。方法 经股动、静脉插管对１４７ 例肺癌行２２１ 次支气管动脉造影和化疗灌注，１３ 例同时作肺动脉造影。均以ＤＳＡ 数字成像系统或电影取像１２５ ～２５ 帧／ｓ。结果 ①原发性肺癌主要为单支体循环动脉供血：支气管动脉占８４ ％ ，１３ 例肺动脉造影均不向肺癌供血。②介入治疗过程中，肺癌供血动脉可发生改变：本组３ 例，原由支气管动脉或肋间动脉供血，经介入治疗几次后而改由其它体循环动脉供血。③转移性肺癌多由支气管动脉供血，一例为肺静脉供血。结论 肺癌的供血情况以动态数字图像显示最为满意，肿瘤染色，肺动静脉瘘等尤其是用ＤＳＡ 为明确。肺癌供血除支气管动脉外，不少由其他体循环动脉供血，甚至肺静脉供血。在介入治疗期间，原供血动脉可以改变，要注意寻找。
Objective To apply a digital image system to dynamically observe the blood circulation of lung cancer. Methods 221 cases of lung cancer were performed with bronchial artery angiography and chemotherapy perfusion through femoral artery and vein catheterization. Thirteen patients underwent pulmonary angiography simultaneously. DSA digital imaging systems or movies were taken from 125 to 25 frames/s. Results 1 Primary lung cancer was mainly monovascular arterial circulation: bronchial arteries accounted for 84%. None of the 13 pulmonary angiograms supplied blood to lung cancer. 2 During the interventional treatment, the blood supply artery of lung cancer can be changed: 3 cases in this group were originally supplied by bronchial arteries or intercostal arteries, and were changed to several other systemic arteries for blood supply after interventional therapy. 3 Metastatic lung cancer is mostly supplied by bronchial arteries, and one case is pulmonary venous blood supply. Conclusions The blood supply of lung cancer is most satisfactory with dynamic digital images. Tumor staining, pulmonary arteriovenous fistula, etc. are particularly clear with DSA. In addition to bronchial arteries, blood supply to lung cancer is often provided by other systemic arteries, even pulmonary veins. During the interventional period, the original blood supply artery can be changed and care must be taken to find it.
