目的　探讨经胸廓内动脉化学栓塞治疗中晚期肺癌的近期临床疗效。方法　 8例患者造影显示肿瘤的主要供血动脉为胸廓内动脉 ,用不锈钢圈在肿瘤供血分支以下栓塞胸廓内动脉以保护非肿瘤分支避免意外栓塞 ,透视下向肿瘤供血分支内缓慢注入碘化油与顺铂、丝裂霉素乳化剂至血流停止 ,后用明胶海绵条栓塞该分支以减少血流对碘化油的冲洗。结果　介入术后患者症状明显改善 ,4周后复查CT显示碘油在肿瘤内分布良好。结论　对胸廓内动脉供血为主的中晚期肺癌有必要进行化学栓塞治疗。 Objective To investigate the short-term clinical efficacy of transcatheter arterial chemoembolization for advanced lung cancer. Methods Eight patients underwent angiography showed that the main artery of the tumor was the internal thoracic artery. Stainless steel rings were used to embolize the internal thoracic artery below the tumor-supplying branches to protect the non-tumor branches from accidental embolism. Slowly inject iodized oil into the tumor- Cisplatin, mitomycin emulsifier to stop the blood flow, embolization of the branch with gelatin sponge to reduce the flow of iodized oil flushing. Results The symptoms of patients after interventional therapy were significantly improved. CT examination after 4 weeks showed that lipiodol was well distributed in the tumor. Conclusions It is necessary to carry out chemoembolization in advanced stage lung cancer which is the main supply of internal thoracic artery.
