目的：为探讨肺癌介入治疗宜采用的动脉，研究肺癌组织内肺动脉的立体构筑。方法：５ 例手术切除肺癌标本应用１０ ％ ＡＢＳ丙酮液从肺动脉高压灌注进行肿瘤血管铸型，并在立体显微镜下观察肺癌组织肺动脉立体构筑。７８ 例支气管动脉造影资料进行回顾性分析。光学显微镜下观察肺癌组织内毛细血管床。结果：按动脉分布，肺癌组织可分为三个不同区带：支气管动脉主要供应肺癌的中心区；肺癌外带肺动脉相对密集，呈向心直行并互相吻合；癌周组织带有粗大纡曲走行的动脉，向肺癌组织内或包膜内延伸。结论：证实肺动脉参与肺癌供血。认为晚期肺癌单纯支气管动脉灌注化疗（ＢＡＩ）中，宜辅以肺动脉灌注化疗（ＰＡＩ）。
Objective: To study the suitable arteries for interventional treatment of lung cancer and study the three-dimensional structure of pulmonary arteries in lung cancer. Methods: 5 cases of surgical resection of lung cancer specimens were treated with 10% ABS acetone solution from pulmonary artery perfusion to perform tumor vascular casting, and the three-dimensional microscope was used to observe the three-dimensional structure of lung tissue in lung cancer. 78 cases of bronchial arteriography were retrospectively analyzed. Observe the capillary bed in lung cancer tissue under light microscope. Results: According to the distribution of arteries, lung cancer tissue can be divided into three different zones: bronchial artery mainly supplies the central area of lung cancer; pulmonary tumors outside the lung are relatively dense, showing a straight line to the heart and anastomosis; cancer tissue with a large twist The artery extends into or within the lung cancer tissue. Conclusion: It was confirmed that pulmonary artery involved in lung cancer. It is considered that pulmonary arterial infusion chemotherapy (PAI) should be used in advanced bronchial arterial infusion chemotherapy (BAI) for advanced lung cancer.
