ABSTRACT
Objective To explore the effects and complication treatments of microwave ablation(MWA) for benign thyroid nodules.Methods The clinical data of 74 patients with benign thyroid nodules treated with MWA in our department from June 2014 to May 2015 were collected and studied retrospectively.Furthermore,the effects and complication treatments were analyzed and calculated.Results A total of 93 nodules were treated with MWA,of which 46 were the main nodules,cystic 47;7 nodules' ablation were not complete,the complete ablation rate was 92.47％.The postoperative reduction of volume in cystic nodules were significantly higher than solid nodules,and the number of solid nodules decreased more rapidly postoperation.The untreated cystic nodules developed a certain degree of growth after 6 months of surgery.After treatment,the TSH of solid nodules were obviously higher,the FT3 and FT4 were much lower than those before treatment and cystic nodules(P ＜ 0.05).A total of 17 cases of complications occurred in the positive symptomatic treatment,all cases were cured within a few days,there was no serious complications.Conclusion Microwave ablation has a high ablation rate in the treatment of thyroid benign nodules,the ablation effects are different between solid and cystic nodules;early and targeted measures can effectively prevent and deal with surgical complication.
