目的探讨千叶针引导射频针穿刺技术在肝癌射频消融治疗中的作用。方法选择原发性肝癌患者48例,采用CT下千叶针引导射频针穿刺技术对其行射频消融治疗,观察其穿刺成功率,分析其不良反应和并发症。结果千叶针一次到位者236位点(72.6%),射频针一次到位者318位点(97.8%)。与穿刺有关的并发症:少量气胸1例(2.1%),肝包膜下出血2例(4.2%),无腹腔内出血,胆囊穿孔,结肠穿孔等严重并发症出现。结论千叶针引导射频针穿刺技术可使每个位点射频针一次穿刺成功率与准确率大大提高,并发症发生率降低,可在肝癌的射频治疗中推广应用。
Objective To investigate the effect of chirual-needle guided radiofrequency needle aspiration in radiofrequency ablation of liver cancer. Methods Forty-eight patients with primary liver cancer were selected. Radiofrequency catheter ablation was performed with Chisel needle guided radiofrequency needle aspiration. The puncture success rate was observed, and the adverse reactions and complications were analyzed. Results Thousands of needles were once placed in 236 sites (72.6%), while RF needles were once in 318 sites (97.8%). Complications associated with puncture: a small amount of pneumothorax in 1 case (2.1%), subhepatic hemorrhage in 2 cases (4.2%), no intra-abdominal bleeding, gallbladder perforation, colon perforation and other serious complications. Conclusion Chiffon-guided radiofrequency needle aspiration technique can greatly improve the success rate and accuracy of puncturing the RF needle at each site, and reduce the complication rate. It can be widely used in the radiofrequency ablation of liver cancer.
