肺癌介入治疗中体-肺分流的研究(附167例分析)

目的：了解原发性肺癌支气管动脉造影中出现的体肺分流征象及其对ＢＡＩ 疗效的影响。材料与方法：对１６７例原发性肺癌患者在介入治疗前行支气管动脉造影，注射造影剂后１ 、３ 、５ｓ 观察是否提前出现体肺分流。结果：１６７ 例中出现体肺分流者６６ 例，占３９ ．５ ％ ，体肺分流与肺癌的组织类型及肿块大小无明显关系，而与肿块的发生部位有关，中心型肺癌比周围型多。结论：体肺分流发生的形式中以支气管动脉与肺动脉者最多，分流发生的原因是因为肿瘤侵及肺动脉、奇静脉，又与瘤内新生血管相通，分流血管少不影响ＢＡＩ 疗效，多则影响疗效。

The Study on B P Shunt or B Az Shunt in Pulmonary Carcinoma Appearing during Interventional Treatment (An Analysis of 167 Cases)

Purpose: To evaluate the imaging manifestations of B P shunt during bronchial arteriography of lung cancer and its influence on therapeutic effect of BAI. Materials and Methods:167 cases of primary lung cancer underwent bronchial artery infusion and the early B P shunt was determined at 1, 3 and 5 seconds after injecting contrast media. Results:The B P or B Az shunt appeared in 66 cases (39.5%). The results showed that B P shunt had no relation with the histologic type or the size of the tumor, but closly related with the location of the tumor. The rate of shunts in central lesions was higher than that in peripheral. Conclusion:Most of the shunts occur between bronchial and pulmonary artery. The reasons of shunts are infiltration of vessels and connection with newly formed vascularity within the tumor. The therapeutic effect will not be influenced if the shunt vessels are sparse.
