目的　研究微导管栓塞技术在小肝癌治疗中的临床价值。方法　 2 6例单结节小肝癌 (原发性 2 3例 ,转移性 3例 )接受了 83次微导管栓塞术治疗。其中 ,施行瘤内热碘油栓塞术 80次 (2 6例 ) ,载瘤动脉保护性微弹簧圈栓塞术 2次 ,瘤内动 静脉瘘无水酒精栓塞术 1次。结果　 2 6例均获得瘤体内完全性、充填性热碘油栓塞。 2例施行了手术切除 ,病理检查显示 :癌组织坏死 10 0 %。全组平均随访 35个月 (14～ 5 5个月 ) ,患者均存活 ,未发生严重并发症。结论　采用微导管栓塞技术治疗小肝癌的初步结果似乎与外科手术具可比性 ,能否替代手术尚需进一步随防研究和积累病例 Objective To study the clinical value of microcatheter embolization in the treatment of small hepatocellular carcinoma. Methods Twenty-six patients with small nodular hepatocellular carcinoma (primary 23 cases, metastatic 3 cases) received 83 microcatheter embolizations. Among them, 80 intratumor thermal lipiodol embolization procedures (26 cases) were performed, tumor-bearing arterial protective microcoil embolization was performed twice, and intratumoral arteriovenous fistula was administered with alcohol embolization once. Results Twenty-six patients achieved complete intracranial thermolipin embolization. Two patients underwent surgical resection. Pathological examination showed that the tissue necrosis was 10%. The average follow-up of the whole group was 35 months (14 to 55 months). All patients survived without serious complications. Conclusion The preliminary results of microcatheter embolization for the treatment of small hepatocellular carcinoma seem to be comparable with surgical procedures. The need for further follow-up studies and the accumulation of cases is a substitute for surgery.
