目的探讨射频消融(radiofrequency ablation,RFA)联合醋酸加氯化钠治疗肝肿瘤对消融体积的影响。方法12例直径>5cm的肝肿瘤患者分为治疗组(6例)和对照组(6例),治疗组在术中先行单次RFA联合醋酸加氯化钠治疗,对照组行单纯RFA治疗,两组均在治疗后切除肿瘤,观察毁损体积。结果治疗组单次治疗后肿瘤毁损长径6.11cm,短径5.26cm;对照组肿瘤毁损长径3.66cm,短径3.25cm。结论RFA联合醋酸加氯化钠治疗肝肿瘤可使一次性毁损体积增加,治疗时间相对延长。
Objective To investigate the effect of radiofrequency ablation (RFA) plus acetic acid plus sodium chloride on the ablation volume of liver tumors. Methods Twelve patients with liver tumors> 5cm in diameter were divided into treatment group (6 cases) and control group (6 cases). The treatment group received single RFA plus acetic acid plus sodium chloride during operation and the control group received RFA alone. The tumors were excised after treatment and the volume of the lesion was observed. Results After the single treatment in the treatment group, the length of the tumor lesion was 6.11 cm in diameter and 5.26 cm in diameter. In the control group, the diameter of the lesion was 3.66 cm in diameter and 3.25 cm in diameter. Conclusion RFA combined with acetic acid and sodium chloride in the treatment of liver tumors can make one-time damage volume increased, the treatment time is relatively longer.
