B超引导下多弹头射频治疗肝癌45例

目的 :总结多弹头射频治疗肝癌的近期疗效、适应证与并发症。方法 :对 45例肝癌患者行 60次射频治疗 ,通过治疗前后肿瘤大小的比较 ,患者自觉症状的改善情况和AFP值改变进行对比观察。结果 :5 5例次于治疗后 10天 ,3 0例次于治疗后 3 0天 ,10例次于治疗后 60天 ,进行了彩色B超及CT复查 ,10天后 70 %患者肿瘤体积缩小在2 0 %以上 ,3 0天后 80 %患者肿瘤体积缩小在 3 0 %以上 ,部分瘤体钙化或呈均质低密度区。 60天后 3例患者肿瘤体积缩小在 5 0 %以上。与术前相比全部瘤体内血供消失。 80 %患者自觉症状改善、其AFP值下降者占 5 0 % ,无手术死亡 ,术后并发症为 2 5 %。结论 :B超引导下多弹头射频治疗中晚期肝癌效果确切而满意。

Ultrasonically Guided Radio-frequency Ablation of Liver Tumors with A Clustered Electrode: A Report of 45 Cases

Objective:To evaluate the efficacy of ultrasonically guided radio-frequency (RF) thermal ablation of liver tumors with a clustered electrode.Methods:Clinical records of 45 consecutive patients who underwent RF tissue ablation 60 times were analysed. Image data, tumor size, clinic manifestation, and AFP value before and after the procedure were compared.Results:55 cases at 10 days, thirty at 30 days, ten at 60 days after the procedure were subjected to color utrasonography and CT scans, respectively. The tumor size decreased by 20% at 10 days in 70% patients, decreased by 30% at 30 days in 80% patients, decreased by 50% at 60 days in 3 patients. AFP value decreased in 50% of patients, no operative death was noted, and the rate of operative complication was 25% after ablation.Conclusions:Ultrasound guided RF thermal ablation of hepatic tumors is safe, applicable and effective.
