良性甲状腺结节B超导向无水乙醇介入治疗的临床研究

Treatment of benign thyroid nodules by percutaneous ethanol injection under guidance of ultrasonography

目的 探讨B超导向经皮无水乙醇注射 (PercutaneousEthanolInjectionPEI)治疗良性甲状腺结节的疗效及临床价值。方法 PEI治疗 17例良性甲状腺结节 ,平均注射乙醇量为甲状腺结节治疗前容积的 1 2 7倍。结果 治疗后的甲状腺容积显著缩小 ,平均缩小 74%,未见明显副作用。结论 PEI是一种安全有效的治疗良性甲状腺结节的非手术疗法。

Objective To evaluate the efficiency of percutaneous ethanol injection(PEI) guided by ultrasonography on the treatment of benign thyroid nodules.Methods Seventeen patients with benign thyroid nodules underwent PEI.The total amount of anhydrous ethanol injection was approximately 1.27 times the volume of thyroid nodule before treatment.Results After injection the volume of the nodules decreased markedly.The mean percentage of nodules shrinkage was 74%.No obvious adverse effect was observed during therapy.Conclusion PEI is an effective and safe therapy for benign thyroid nodules as an alternative of surgery.
