目的 评估经皮注射无水酒精治疗小肝癌的疗效。方法 1 8例原发性肝癌 2 2个病灶 (直径 <3.3cm)接受经皮注射无水酒精的治疗。在 CT引导下将细针穿入病灶中央 ,缓慢地注入无水酒精。随访采用螺旋 CT增强扫描的办法进行 ,同时观察并发症发生情况。结果 2 1个病灶平均肿瘤直径 2 .3cm (1 .5～ 3.3cm ) ,平均注射酒精量 5 .8ml (3～ 9ml)。 1 7个病灶治疗后肿瘤组织全部坏死 ,4个病灶显示有残留肿瘤。并发症包括腹部剧痛(5 .5 5 % )、肝节段性梗塞 (5 .5 5 % )。结论 经皮注射无水酒精治疗小肝癌是安全有效的
Objective To evaluate the efficacy of percutaneous injection of anhydrous alcohol in the treatment of small hepatocellular carcinoma. Methods Twenty-eight cases of primary hepatocellular carcinoma were treated with percutaneous injection of anhydrous alcohol in 22 lesions (diameter <3.3cm). Under the guidance of CT, the fine needle penetrates the center of the lesion, slowly injecting anhydrous alcohol. Follow-up with spiral CT enhanced scan approach, while observing the incidence of complications. Results The average tumor diameter of 2 lesions was 2.3 cm (1.5-3.3 cm) and the mean volume of injected alcohol was 5.8 ml (3-9 ml). Seventeen lesions were completely necrotic after treatment, and four lesions showed residual tumor. Complications included abdominal pain (5.55%) and hepatic segmental infarction (5.5.5%). Conclusion Percutaneous injection of anhydrous alcohol in the treatment of small hepatocellular carcinoma is safe and effective
