目的 评价CT导引经皮注射无水乙醇 (CT PEI)治疗甲状腺腺瘤的安全性和疗效。方法 5 4例病人 ,共 73个结节 ,经穿刺细胞学检查证实为甲状腺腺瘤。三碘甲状腺原氨酸 (T3)、血清甲状腺素 (T4)、促甲状腺激素 (TSH)检查正常。CT PEI治疗甲状腺腺瘤。 73个结节内共行PEI 115次 ,平均 ( 1 5 8± 0 78)次 /结节 ,结节体积的乙醇注入量为 0 3～ 2 5ml/cm3。结果 治疗后 3～ 6个月行CT复查 ,肿瘤完全消失者 3 7个 ,体积缩小在 80 %以上者 2 8个 ,体积缩小 5 0 %～ 80 %者 7个 ,1个体积缩小 2 8 9%。 5 4例病人中 1例出现一过性声音嘶哑 ,2例出现局部红肿疼痛、烧灼感。结论 CT PEI治疗甲状腺腺瘤是一种安全、有效、副作用少、微创的手术方法。
Objective To evaluate the safety and efficacy of CT-guided percutaneous injection of absolute ethanol (CT PEI) in the treatment of thyroid adenomas. Methods A total of 73 nodules in 54 patients were confirmed by puncture cytology as thyroid adenomas. Triiodothyronine (T3), serum thyroxine (T4), and thyroid stimulating hormone (TSH) were normal. CT PEI treatment of thyroid adenomas. Among the 73 nodules, there were a total of 115 PEIs with an average (158±0.88)/nodules, and the nodule volume of ethanol injection was 0.3 to 2.5 ml/cm3. Results 3 to 6 months after treatment, CT examination was performed. The total disappearance of tumors was 37, the volume was reduced to more than 80%, 28 were reduced, the volume was reduced by 50% to 80%, and 1 volume was reduced by 2.8. %. In 5 of 4 patients, one case had transient hoarseness, and 2 cases had localized redness, pain, and burning sensation. Conclusion CT PEI treatment of thyroid adenoma is a safe, effective, minimally invasive surgical method.
