彩色多普勒超声观察经皮无水酒精注射疗法和经皮高温蒸馏水注射疗法治疗肝细胞癌

目的探讨彩超在经皮无水酒精注射（PEI）和经皮高温蒸馏水注射（PHDI）介入治疗肝细胞癌（HCC）的应用价值。方法40例HCC患者分为PEIT20例、PHDI20例,两组在病情、病程、病变程度、分类、年龄、性别、肿瘤大小和肿块数等方面无显著差异。所有病例于治疗前1天、治疗后1周、2周、1个月分别接受彩超检查,观察肿瘤的大小变化,检测肿瘤周边及内部的血流信息。结果PEIT和PHDI治疗前后肿瘤直径减小差异均有显著统计学意义（P〈0.001,P〈0.01）,PEIT治疗后肿瘤直径减小与PHDI比较差异也有统计学意义（P〈0.05）;两组治疗前后肿瘤血供均有显著变化（P〈0.05）。结论PEIT和PHDI均能明显减少肿瘤内部血供,PEIT治疗后肿瘤直径缩小较PHDI明显。彩超能准确地显示介入治疗后肿瘤大小的改变和肿瘤内部血供的变化,实时监控介入治疗过程,对疗效进行评估。

Value of color Doppler ultrasonography in interventional treatment of HCC with percutaneous injection of ethanol and hyperthermal distilled-water

Objective To assess the value of color Doppler ultrasonography in interventional treatment of hepatocellular carcinoma(HCC)with percutaneous injection of ethanol(PEI)and percutaneous hyperthermal distilled-water injection(PHDI).Methods Forty patients with HCC were divided into two groups.Each group had 20 patients and was treated by percutaneous injection of ethanol(PEI)and hyperthermal distilled-water(PHDI),respectively.There was no significant difference between age,sex,grade,history,and size of tumor in ...
