目的 探讨微导管在肝癌化疗性栓塞中的作用。方法将４Ｆ～５ＦＹａｓｈｉｒｏ、Ｋｏｕｎｏ亲水超滑导管、５Ｆ牧羊钩导管作为导引导管插入肝总或肝固有动脉及肠系膜上动脉，３Ｆ微导管经导引导管置入肝段或肿瘤滋养动脉施行肝癌化疗性栓塞术。结果本组３５例共行化疗性栓塞５０例次，其中１６例小肝癌行肝段栓塞，１９例非小肝癌但癌灶尚局限者行左／右叶或右叶前、后叶栓塞。随访ｌ～２年生存期分别为１００％、８７．５％及５２．６％、４２．ｌ％。术后肝功能损害轻微，元并发症。结论在小肝癌、非小肝癌但癌灶尚局限者或伴有肝动脉异常迂曲、损伤后狭窄、发育变异的情况下，使用微导管提高栓塞精度对改善疗效和避免并发症具有十分重要的临床应用价值。
Objective To investigate the role of microcatheters in the chemotherapy embolization of liver cancer. Methods 4F-5FYashiro, Kouno hydrophilic superslide catheter, 5F shepherd hook catheter were used as guiding catheter to insert the total hepatic artery or hepatic artery and superior mesenteric artery. 3F microcatheter was placed into the liver segment or tumor nourishing artery for guiding liver cancer. Chemoembolization. RESULTS: Thirty-five patients in this group underwent chemotherapy embolization in 50 cases, of which 16 cases of small hepatocellular carcinoma were performed with hepatic segment embolization, and 19 cases of non-small hepatocellular carcinoma with localized left or right lobe or right lobe anterior and posterior embolization. Follow-up l ~ 2 years of survival were 100%, 87.5% and 52.6%, 42. l%. Mild postoperative liver damage, meta-complications. Conclusion In the case of small hepatocellular carcinoma, non-small hepatocellular carcinoma, but with limited focal lesions or accompanied by hepatic arterial abnormalities, post-injury stenosis, and developmental variability, the use of microcatheters to improve the accuracy of embolization has important clinical implications for improving efficacy and avoiding complications. Value.
