目的探讨倾斜穿刺技术在CT引导下冷循环射频消融(RFA)治疗膈顶部肝癌的应用价值。方法在CT引导下运用倾斜穿刺技术穿刺19例肝癌患者共21个膈顶部病灶,并进行冷循环RFA术,术后复查增强CT或MR,观察病灶坏死情况。结果 19个病灶完全坏死,2个病灶大部分坏死,病灶完全坏死率90.5%,无严重并发症。结论应用CT引导下倾斜穿刺技术RFA治疗膈顶部肝癌效果满意,值得进一步的研究和总结。
Objective To investigate the clinical value of oblique puncture technique in the treatment of the top of diaphragm phrenic liver cancer under the guidance of CT-guided cold cycle radiofrequency ablation (RFA). Methods Twenty - one cases of 21 patients with hepatocellular carcinoma were treated by CT guided CT angiography. Twenty - one of the 19 patients with HCC were treated by cold circulation RFA. Postoperative CT or MR imaging was performed to observe the lesion ’s necrosis. Results 19 lesions were completely necrotic, most of 2 lesions were necrotic, and the complete necrosis rate was 90.5%. There was no serious complication. Conclusion The application of CT-guided oblique angioplasty RFA in the treatment of the top of the diaphragm is satisfactory and worthy of further study and summary.
