目的评价经肝动脉导管血管内注射无水乙醇碘化油乳剂栓塞治疗肝癌动静脉瘘的可行性及临床疗效。方法对22例肝癌动静脉瘘血管分别行超选择性插管注射无水乙醇碘化油乳剂,造影观察动静脉瘘闭塞情况及肿瘤的栓塞情况。结果22例肝癌动静脉瘘经肝动脉导管血管内注射无水乙醇碘化油乳剂2~15 ml,对分流量大的动静脉瘘配合明胶海绵栓塞。造影显示瘘口全部闭塞,未见明显不良反应,肿瘤栓塞密实。结论经肝动脉导管注射无水乙醇碘化油乳剂治疗肝癌动静脉瘘,疗效可靠,不影响对肿瘤的栓塞治疗。
Objective To evaluate the feasibility and clinical efficacy of transcatheter hepatic arteriovenous fistula with hepatic arterial catheterization of ethanol-iodized oil emulsion embolization. Methods Twenty-two patients with arteriovenous fistula of liver cancer were injected with anhydrous ethanol iodized oil emulsion through selective cannulation. Angiography was performed to observe the occlusion of arteriovenous fistula and the embolization of the tumor. Results Twenty-two HCC arteriovenous fistulas were injected intravascularly with 2-15 ml anhydrous ethanol iodized oil emulsion via the hepatic artery catheter. The arteriovenous fistula with large fractionation was treated with gelatin sponge embolization. Angiography showed complete occlusion of the fistula, no significant adverse reactions, dense tumor embolization. Conclusion Intrahepatic arterial catheter injection of anhydrous ethanol iodized oil emulsion for the treatment of liver cancer arteriovenous fistula, reliable, does not affect the embolization of the tumor treatment.
