CT引导下经皮无水乙醇注射治疗肝癌门静脉瘤栓

目的探讨CT引导下经皮无水乙醇注射治疗肝癌门静脉瘤栓的疗效。方法对20例肝癌伴门静脉瘤栓患者,进行CT引导下门静脉瘤栓内无水乙醇注射治疗。每周1～2次,1～3次为一疗程,每例1～2个疗程,疗程间隔1个月,治疗后随访6个月～5年。结果20例中,17例(85%)瘤栓有不同程度改善,其中2例(10%)瘤栓消失,15例(75%)瘤栓缩小或无进展,3例(15%)无效。结论CT引导下经皮注射无水乙醇治疗门静脉瘤栓是一种有效治疗方法,治疗病例的选择是取得良好疗效的关键。

Treatment of portal vein tumor emboli of hepatocellular carcinoma with CT-guided percutaneous ethanol injection

Objective To evaluate the curative effects of portal vein tumor emboli(PVTE)of hepatocellular carcinoma treated by CT-guided percutaneous ethanol injection(PEI).Methods Absolute ethanol was injected into the tumor embolus of portal vein guided by CT in twenty patients with hepatocellular carcinomas.The procedure was carried out one or two times each week one to three times as a course and one to two courses for a patient.The interval between two courses was one month and the patients were followed up for 6 months-5 years.Results Among the twenty patients,17(85%)were improved in different degrees after the treatment,with disappearence of the tumor emboli in 2(10%)and size stability or even smaller in 15 (75%),and finally no response in 3(15%).Conclusions CT-guided PEI is an effective method for patient with PVTE and proper selection of patient for the procedure is the key to obtain better curative effects.
