超声引导下微波消融治疗甲状腺良性结节的临床效果及安全性评估OA

Objective To investigate the clinical effect and safety of ultrasound-guided microwave ablation(MWA)in the treatment of benign thyroid nodules.Methods A retrospective analysis was conducted on patients with benign thyroid nodules who were admitted to our hospital from June 2022 to December 2024.Patients who met the inclusion criteria underwent ultrasound-guided MWA.The nodule volume reduction rate(VRR)was statistically analyzed at 1,3,6,and 12 months postoperatively.Meanwhile,the neck symptom score and cosmetic score were compared between preoperative and 12-month postoperative assessments,and the occurrence of postoperative complications was recorded.Results A total of 59 nodules were detected in 50 patients,including 31 solid nodules and 28 cystic-solid nodules.The nodule VRRs at 1,3,6,and 12 months postoperatively were 44.36％(25.00％～67.55％),72.46％(63.96％～80.23％),84.40％(75.00％～92.20％),and 91.07％(84.74％～96.21％),respectively.At 12 months postoperatively,both the neck symptom score and cosmetic score were significantly lower than those before surgery,with statistically significant differences(P＜0.05).After surgery,the incidence of pain was 4％,and the incidence of hoarse voice was 2％;no major complications were observed.Conclusions Ultrasound-guided MWA can effectively reduce the volume of benign thyroid nodules with a low incidence of postoperative complications,which possesses high value for clinical promotion and application.
