“…Nevertheless, only a few studies considering MWA efficacy in the treatment of benign solid thyroid nodules are available. In these studies, at the post-treatment follow-up (from 1 to 12 months), nodule volume reduction ranged from 45 to 65 % [76,77,81,82]. Feng et al reported an improvement of symptoms and cosmetic score [77].…”

“…Slight fever was found in three patients, but lasted only one day [77]. 3-9 % of patients complained of voice changes, all recovering spontaneously within 3 months; in one case, treatment with corticosteroid was necessary [76,77]. Hemorrhage was reported in nearly 40 % of cases [77].…”

“…After the antenna is placed, an endovenous unconscious anesthesia is administered. According to Yue et al, a mixture of 0.9 % of lidocaine and saline should be infused into the surrounding thyroid capsule to achieve a ''liquid isolating region,'' protecting the vital structure of the neck [76]. Energy ranging from 20 to 50 W is usually used.…”

“…The therapy continues until the whole nodule becomes hyperechoic. At the end of the treatment, the patient remains under observation for 30 min, with compression of the neck to prevent hematoma formation [76,77].…”

Image-guided thermal ablation of benign thyroid nodules

Benign thyroid nodules are a common disease in the general population. Most often, they are completely asymptomatic and discovered occasionally during routine ultrasound examinations, and do not require any treatment. When thyroid nodules become symptomatic, surgical excision is still considered standard treatment. In the last few years, several experiences in the treatment of benign thyroid nodules through image-guided percutaneous thermal ablation have been reported with encouraging results, so that currently, these treatments are often proposed as first-choice options for patients with symptomatic benign thyroid nodules. In this paper, we discuss the present literature on the topic, focusing on different techniques available for image-guided percutaneous ablation, particularly radiofrequency (RFA), laser (LA), microwave (MWA), and high-intensity-focus ultrasound (HIFU). Little evidence about the efficacy of MWA and HIFU is now available. According to the literature, good results have been obtained with RFA and LA. Regarding RFA, volume reduction after ablative treatment has been found to range from 47 to 84 % at 3-6 months, and from 62 to 93 % at 1 year; LA also seems to be effective in achieving shrinkage of thyroid nodules, with volume reduction from 37 to 81 % at 3-6 months, and from 13 to 82 % at 1-year follow-up. Moreover, applications of advanced image-guidance modality, such as contrast-enhanced ultrasound and virtual navigation with fusion imaging, are discussed.Keywords Laser Á Radiofrequency Á Microwave Á Highintensity focused ultrasound Á Thyroid nodule SOMMARIO I noduli benigni della tiroide sono una evenienza comune nella popolazione generale. Più spesso vengono scoperti occasionalmente durante un esame ecografico fatto per altri motivi, sono asintomatici e non richiedono alcun trattamento. Qualora i noduli diventino sintomatici, l'escissione chirurgica è ancora considerato il trattamento standard. Tuttavia, negli ultimi anni, è cresciuta l'esperienza circa il trattamento di tali noduli tramite ablazione percutanea sotto guida ecografica tanto che, attualmente, questo viene spesso proposto come trattamento di scelta. Lo scopo del nostro lavoro è fare una revisione della letteratura riguardante l'argomento, con un particolare focus sulle differenti tecniche attualmente a disposizione, in particolare radiofrequenza (RFA), laser (LA), microonde (MWA) e high-intensity-focus ultrasound (HIFU). Al momento ci sono ancora poche evidenze sull'efficacia di MWA e HIFU. Secondo quanto riportato in letteratura, buoni risultati sono stati ottenuti con RFA e LA. Riguardo la radiofrequenza, la riduzione volumetrica dopo la procedura ablativa va da 47 a 84 % a 3-6 mesi e da 62 a 93 % a 1 anno; anche il laser sembra essere efficace nel causare la riduzione del nodulo, con percentuali che vanno da 37 a 81 % a 3-6-mesi a da 13 a 82 % a 1 anno di follow-up Abbiamo poi discusso brevemente le

Image‐guided chemical and thermal ablations for thyroid disease: Review of efficacy and complications

et al. 2018

View full text Add to dashboard Cite

Image-guided ablation of thyroid disease is increasingly being commonly reported. Techniques including ethanol injection and thermal ablation using radio-frequency, laser, and microwave devices have been described. Minimally invasive approaches to the management of benign cystic, solid, and functional thyroid nodules as well as both primary and recurrent thyroid malignancy have been reported. The purpose of this article is to review the current evidence relating to image-guided ablation of thyroid disease with a focus on clinical outcomes and complication rates for patients treated with this minimally invasive approach.
