RESUMO
INTRODUCTION: Radiofrequency ablation (RFA) plays an increasing role in the management of thyroid nodules. The purpose of this study was to evaluate the safety and efficacy of RFA of benign thyroid nodules in terms of volume reduction and symptom relief. METHODS: We reviewed the medical records of patients with a solitary thyroid nodule who received RFA at our centre from April 2016 to January 2020. Ultrasound-guided RFA was performed by the moving-shot technique. Patients were followed up with ultrasound examinations and thyroid function tests. We evaluated changes in volume and in compressive (0-10 scale) and cosmetic (4-point scale) symptoms to analyse efficacy and complications, and in thyroid function to evaluate safety. RESULTS: A total of 72 patients were included in the study. The mean follow-up was 11.1±0.7 months. There was a statistically significant reduction in size of the nodules at Month 1, 3, 6 and 12 after RFA (expressed as volume reduction rate: 34%±2.1, 50.8%±2.2, 60.3%±2.6, 58.87%±3.5, p<0.0001). We found statistically significant improvement in compressive symptoms (from 7.1±0.26 to 1.76±0.33, p<0.0001) and in cosmetic alteration (from 3.66±0.09 to 2.14±0.14, p<0.0001). No major complications were observed. DISCUSSION: RFA achieved significant volume reduction and improved compressive symptoms as well as cosmetic complaints, with minimum side effects. Our results are in line with recent available evidence and further support the use of RFA as a safe and effective therapeutic option in the management of benign thyroid nodules.

La mayoría de los pacientes con Fístula Arteriovenosa Pulmonar (FAVP) no se reconocen clínicamente hasta que son adultos. Los síntomas, si ocurren, pueden no ser específicos, encontrándose hemoptisis, epíxtasis y saturaciones bajas de oxígeno entre otros. En la radiografía simple aparecen como una masa redondeada u oval, lobulada y de densidad uniforme; muchas veces permite el diagnóstico, ya que son visibles los vasos arterial y venoso. La TC helicoidal con contraste o la angio-RM son ideales para la evaluación preterapéutica, identificándose la arteria nutriente desde el hilio pulmonar y la vena de drenaje hacia la aurícula izquierda. Con la embolización mediante catéter con coils, se obtienen excelentes resultados (AU)
