目的:观察冷循环射频消融治疗非手术适应证肝癌的近期疗效。方法:采用cool-tip公司生产的单极冷循环射频治疗机对35例肝癌患者57个病灶进行了射频消融治疗,根据治疗前后超声造影和CT结果、AFP变化评价疗效。结果:57个病灶均出现不同程度的消融,术后CECT及CEUS检查证实41个(71.9%)病灶得到完全消融;16个病灶(28.1%)为不完全消融。22例术前血清AFP升高者术后2个月19例AFP均有下降。结论:RFA治疗非手术适应证肝脏肿瘤近期疗效较满意,无严重并发症发生。
Objective: To observe the short-term curative effect of cold cycle radiofrequency ablation on non-surgical indications of liver cancer. Methods: Fifty-five patients with liver cancer undergoing radiofrequency ablation were treated with cool-tip unipolar cold-cycle radiofrequency ablation. The changes of AFP were evaluated according to the results of contrast-enhanced ultrasound and CT before and after treatment. Results: Fifty-seven lesions were ablated to varying degrees. CECT and CEUS showed that 41 (71.9%) lesions were completely ablated and 16 lesions (28.1%) were incomplete ablation. Twenty-two patients with elevated serum AFP before surgery had a decrease in 19 AFPs at 2 months after operation. Conclusion: The short-term efficacy of RFA in the treatment of non-surgical indications of liver tumors is satisfactory, without serious complications.
