超声引导经皮穿刺无水酒精注射治疗甲状腺囊肿疗效观察

Tneatment of thyroid cystic nodule by ultrasound guided percutaneous ethanol injection

目的探讨超声引导下经皮穿刺无水酒精注射(PEI)治疗甲状腺囊肿的临床价值.方法甲状腺囊肿24例.单纯性囊肿6例,复杂性囊肿18例,在超声引导下注射无水酒精,剂量约为囊肿治疗前体积的0.5～1.5倍,治疗后应用超声观察疗效.结果3个月后,甲状腺囊肿体积显著缩小,单纯性囊肿体积缩小率(88.79±4.18)%,有效率100%;复杂性囊肿体积缩小率(81.70±4.68)%,有效率83.33%.无明显副作用.结论超声引导经皮穿刺无水酒精注射治疗甲状腺囊肿疗效显著,是一种安全有效的治疗方法.

Objective To investigate the clinical value of the percutaneouse ethanol injection(PEI) treatment guided by ultrasonography for thyroid cystic nodules (TCNs).Methods Twenty-four cases with thyroid cystic nodules including 6 simple cysts(SC) and 18 complicated cysts(CC) underwent PEI treatment. The total amount of ethanol injected was 0.5 to 1.5 times the volume of thyroid nodule before treatment. The curative effect in thyroid cystic after PEI was observed by ultrasonography.Results After 3 months ,the volume of the TCNs decreased markedly. The mean percentage of nodules shrinkage was 88.79±4.18% in SC and 81.70±4.68% in CC, the efficacy rate was 100% in SC and 83.33% in CC. No obvious side effects were observed during the therapy.Conclusion PEI is an effective and safe therapeutic method for TCNs.
