Clinical analysis of ultrasound-guided microwave ablation for pediatric thyroid nodules- a single center research

Abstract

To provide a new minimally invasive treatment for children with benign thyroid nodules, and to provide clinical data for applying microwave ablation (MWA) to children. A retrospective analysis was conducted on the clinical data of 21 pediatric patients with benign thyroid nodules who underwent ultrasound-guided MWA at the Children's Hospital affiliated with Chongqing Medical University from July 2022 to August 2023. The safety, clinical efficacy, volume reduction ratio and prognostic value of the treatment were evaluated. The participants were followed for at least 4 months (median 7 months, range 4–16 months). The average (range) ablation time for the 21 patients was only(233.90 ± 184.97) (40–660)seconds, with intraoperative bleeding less than 0.5 mL. No complications such as hoarseness, seizures or coughing during drinking water were observed after ablation treatment. All the participants' hormone reflecting thyroid function remained in the normal ranges after treatment. Besides, these hormones at 12 h after surgery and 1 month after surgery were not statistically different from those before surgery. Immediate postoperative ultrasound imaging showed a significant decrease in volume of benign thyroid nodules, the volume of nodules at 1 month postoperatively (M, 1.39), and the volume of nodules at 4 months postoperatively (M, 0.40) significantly smaller than that before surgery (M, 4.94). Ultrasound-guided MWA is a new option for the treatment of benign thyroid nodules in children, with advantages such as minimal invasiveness, good clinical effect, high safety, little damage to thyroid function, short operation time, less intraoperative bleeding, low pain sensation and aesthetic appearance.
