目的:

评价3D iGuide穿刺技术在DynaCT引导射频消融(RFA)治疗大肝癌中的可行性及安全性。

方法:

选取2016年9-12月在解放军总医院介入放射科住院治疗的孤立性大肝癌患者19例,行DynaCT扫描并选择3D iGuide技术引导射频针穿刺后实施RFA术,评价术后的技术成功率、术中及术后并发症、治疗效果。

结果:

19例患者全部操作成功,技术成功率为100%,术中及术后并发症以疼痛为主,并未出现严重并发症;术后1个月影像学复查评估治疗效果,完全缓解(CR)17例、部分缓解(PR)2例。

结论:

3D iGuide穿刺技术在DynaCT引导射频消融治疗大肝癌中安全、有效且操作简便,具有极强的可行性,为RFA治疗肝癌提供新的引导方法。

Objective:

To evaluate the feasibility and safety of the 3D iGuide system for radiofrequency ablation (RFA) induced by Dyna computed tomography (DynaCT) in the treatment of hepatocellular carcinoma.

Methods:

Nineteen patients with hepatocellular carcinoma undergoing TACE treatment in PLA General Hospital from September to December 2016 were examined by DynaCT scanning with 3D iGuide technique to guide RFA and were evaluated using success rate, intraoperative and postoperative complications, and local treatment effect.

Results:

The success rate of the technique was 100%, and the intraoperative and postoperative complication was mainly pain. There was no serious complication. After one month of the operation, the imaging findings were evaluated including complete remission (CR) of 17 cases and partial remission (PR) of 2 cases.

Conclusions:

3D iGuide puncture technology is safe, effective and easy to treat patients with large hepatocellular carcinoma in DynaCT guiding RFA, which is highly feasible and provides a new guidance for RFA treatment of hepatocellular carcinoma.
