超声引导下射频消融治疗结节性甲状腺肿46例报告

目的探讨超声引导下射频消融(radiofrequency ablation,RFA)治疗结节性甲状腺肿的临床效果。方法2009年6月～2010年9月对46例甲状腺良性结节在局部麻醉下行超声引导下RFA治疗,在颈部皮肤取1 mm切口,切开皮肤及皮下组织,将射频针穿刺在结节的中心部位开启射频,应用能量为4～6 W,其中心温度可达95℃。结果均成功行RFA,术中无明显并发症发生,1例出现穿刺部位感染。RFA术后6个月47.8%(22/46)患者结节全部吸收,26.1%(12/46)结节体积较术前缩小≥50%,26.1%(12/26)结节体积较术前缩小25%～50%。结论超声引导下RFA治疗结节性甲状腺肿疗效好、微创优势明显,是一种值得推广的手术方法。

Doppler Ultrasound-guided Radiofrequency Ablation for Nodular Goiter:Report of 46 Cases

Objective To explore the efficacy of Doppler ultrasound-guided radiofrequency ablation(RFA) for benign thyroid nodules.Methods From June 2009 to September 2010,we performed RFA under the guidance by Doppler ultrasonography on 46 patients with benign thyroid nodules.We made a 1-mm incision at the neck,cut the skin and subcutaneous tissues,and then inserted a radiofrequency needle into the center point of the nodules for RFA(4-6 W,center temperature 95 ℃).Results The procedure was completed in all the patients without causing severe complications.One patient developed infection at the puncture site.Six months after the RFA,22 of the patients(47.8%) had all the nodules disappeared,12 patients(26.1%) had the size of the nodules reduced by ≥50%,while in the other 12 patients the nodules were reduced by 25%-50%.Conclusions RFA is a safe,effective,and minimally invasive method for the treatment of nodular goiter.It is worth being widely used.
