Image-guided thermal ablations are increasingly applied in the treatment of renal cancers, under the guidance of ultrasound (US) or computed tomography (CT). Sometimes, multiple ablations are needed. The aim of the present study was to evaluate the long-term results in patients with renal mass treated with radiofrequency ablation (RFA) with both US and CT, with a focus on the multiple ablations rate. 149 patients (median age 67 years) underwent RFA from January 2008 to June 2015. Median tumor diameter was 25 mm (IQR 17–32 mm). Median follow-up was 54 months (IQR 44–68). 27 (18.1%) patients received multiple successful ablations, due to incomplete ablation (10 patients), local tumor progression (8 patients), distant tumor progression (4 patients) or multiple tumor foci (5 patients), with a primary and secondary technical efficacy of 100%. Complications occurred in 13 (8.7%) patients (6 grade A, 5 grade C, 2 grade D). 24 patients died during follow-up, all for causes unrelated to renal cancer. In conclusion, thermal ablations with the guidance of US and CT are safe and effective in the treatment of renal tumors in the long-term period, with a low rate of patients requiring multiple treatments over the course of their disease.

Summary Introduction: In 1998, radiofrequency ablation (VNUS Closure Plus™) was authorised in Germany and Europe for the treatment of superficial reflux. We participated in a clinical registry set up by the manufacturing company in 1998. The aim of this retrospective paper was to analyse the long-term results after radiofrequency ablation. Materials, methods and patients: In 1998, we operated on twelve patients (8 women, 4 men). In accordance with the concept of standard vein stripping surgery, all endovenous ablations were combined with crossectomy or ligature of the saphenopopliteal junction. Each vein was thermally ablated over its entire length and no tumescent anaesthesia was performed. The mean age of the twelve patients was 44.9 years. On ten occasions, the entire length of the great saphenous vein was treated, on one occasion the great saphenous vein at the level of the lower leg and on one occasion the entire length of the small saphenous vein. The mean duration of surgery was 80 minutes. Results: The follow-up period was 3 to 168 months, with a mean duration of 80 months. Six patients were followed up for longer than 120 months. In eight cases, the follow-up examination was performed using duplex ultrasound, in two cases using clinical examination and non-invasive testing, in one case using clinical examination and in one case via a telephone interview.The most frequent perioperative complication, occurring in six cases, was hypaesthesia at the medial malleolus or lower leg. There was one case of perioperative thrombophlebitis of a lateral branch in the lower leg and one case of a third-degree thigh burn with subsequent infection of the great saphenous vein canal. No deep vein thrombosis or pulmonary embolism occurred in any of the operated patients.Of the eleven great saphenous veins treated, one recanalised after 14 months, the others had closed or were no longer detectable on ultrasound. The small saphenous vein treated was also no longer detectable.In one patient, a major recurrence at the saphenofemoral junction with recurrent lateral branches in the thigh and lower leg were determined 168 months after surgery. No recurrent varicosis was determined in the other patients.

BackgroundNearly 20 years after the first feasibility study, minimally invasive ultrasound (US)-guided therapeutic techniques are now considered as a safe and effective alternative to surgery for symptomatic benign thyroid nodules. Radiofrequency ablation (RFA) is one of the most widely used treatment in specialized thyroid centers but, due to the relatively recent introduction into clinical practice, there are limited long-term follow-up studies. Aim of our work was to review the outcomes of RFA on solid nonfunctioning and on autonomous thyroid nodules (AFTN) on a long-time period for assessing the results in term of efficacy, complications, and costs and to compare them to the current indications of RFA.MethodsA systematic review was performed using EMBASE and Medline library data between 2008 and 2021. Seventeen studies evaluated RFA for the treatment of benign solid (nonfunctioning or autonomous) thyroid nodules, with an at least 18 months of follow-up. Data extraction and quality assessment were performed by two endocrinologist according to PRISMA guidelines. Anthropometric data, safety and efficacy parameters were collected.ResultsThe majority of the studies was retrospective study and reported 933 nodules, mostly solid. Baseline volume ranged between 6.1 ± 9.6 and 36.3 ± 59.8 ml. Local analgesia was used and the time duration of the treatment was between 5 ± 2 and 22.1 ± 10.9 min. The volume reduction rate at 12 months ranged from 67% to 75% for the nodule treated with a single procedure and reached to 93.6 ± 9.7% for nodules treated with repeat ablations. The regrowth rate at 12 months ranged from 0% to 34%.ConclusionAll the studies under examination consistently validated the long-term clinical efficacy and the substantial safety of RFA for the treatment of benign thyroid nodules. Thermal ablation, however, is an operator-dependent technique and should be performed in centers with specific expertise. The selection of the patients should be rigorous because the nodule size and the structural and functional characteristics influence the appropriateness and the outcomes of the treatment. Future perspectives as the treatment of micro-papillary thyroid cancer or cervical recurrence need further investigations.
