彩超导向射频联合瘤内无水酒精注射治疗原发性肝癌

目的：探讨彩色超声波导向射频毁损联合瘤内无水酒精注射治疗原发性肝癌的治疗效果和安全性。方法：应用彩超引导下对130例原发性肝癌患进行射频毁损联合瘤内无水酒精治疗和对103例．肝癌患进行射频治疗。比较观察该法治疗组与单纯射频治疗组治疗前后肿瘤大小、血供变化与l临床疗效的关系。结果：该法治疗组与单纯射频治疗组术后肿瘤血供消失和减少率分别为96．1％和67．9％；3个月复查彩超肿瘤缩小25％以上分别为89．2％和81．5％。结论：射频毁损联合无水酒精注射是一种有效治疗肝癌的新方法。同时，彩超为实时观察肝癌血供状态、声像图变化提供重要依据，在指导治疗和判定疗效方面有重要意义。

Treatment for Primary Hepatic Carcinoma by Combining Radio Frequency Thermal Ablation with Ethanol Injection Under the Guidance of Color Doppler Ultrasonography

Objective:To explore the effect and safety of the treatment for hepatic carcinoma by combining radio frequency thermal ablation with ethanol injection under the guidance of color Doppler ultrasonography. Methods:130 cases with primary hepatic carcinoma underwent the treatment by combining radio frequency thermal ablation with ethanol injection under the guidance of color Doppler ultrasonography.103 cases with primary hepatic carcinoma treated by radio frequency thermal ablation only.The comparison was made between this treatment and that of radio frequency thermal ablation alone in terms of size of tumor,changes of blood supply and clinical effect before and after each of these two treatments.Results:The disappearing rate and decreasing rate of blood supply of the tumor was 96.1% and 67.9% respectively for the target group and the group of radio frequency thermal ablation.Ultrasonographic examination three months after each treatment showed that the tumor size decreased 25% in 89.2% cases who were applied with the new treatment and 81.5% of the cases with the treatment of radio frequency thermal ablation. Conclusion:The treatment of combining radio frequency thermal ablation with ethanol injection is an effective new way to treat hepatic carcinoma.Color Doppler imaging provides a reliable basis for observing hepatic carcinoma blood supply and change of ultrasovogram.It is also important to guide and assess the treatment.
