HYPOTHESIS Radiofrequency ablation is a safe and effective treatment for hepatocellular carcinomas 3.1 to 8.0 cm in diameter. DESIGN Case series with prospective data collection. SETTING Tertiary referral center. PATIENTS Eighty-six patients with hepatocellular carcinoma treated with radiofrequency ablation from May 1, 2001, to December 31, 2002, were placed into categories of those with ...

CONTEXT Radiofrequency ablation of pancreatic tumours carries a risk of injury to important structures such as the bile duct and duodenum. We have recently developed an ex-vivo model of radiofrequency ablation of the porcine pancreas. OBJECTIVE This study evaluates the effect of variations in probe temperature, duration of ablation and simulated portal venous flow on radiofrequency-induced in...

We perform this meta-analysis to compare the efficacy and safety of cryoablation versus radiofrequency ablation for patients with cavotricuspid valve isthmus dependent atrial flutter. By searching EMBASE, MEDLINE, PubMed and Cochrane electronic databases from March 1986 to September 2014, 7 randomized clinical trials were included. Acute (risk ratio[RR]: 0.93; P = 0.14) and long-term (RR: 0.94;...

OBJECTIVE To assess the efficacy of radiofrequency ablation for reentrant tachyarrhythmias in children and young adults. SETTING A tertiary cardiac referral centre. PATIENTS AND INTERVENTIONS Over a 16 month period 22 patients aged less than 20 years (median age 16.5 years) underwent 26 radiofrequency ablation procedures for atrioventricular reentry tachycardia through an accessory pathway....

Paroxysmal atrial fibrillation can be eliminated with continuous circular linear lesions around the pulmonary veins using radiofrequency ablation. Due to the technical complexity of this procedure balloon-based devices have been developed to simplify pulmonary vein isolation. Cryoballoon ablation provides excellent safety and is technically less demanding when compared to radiofrequency cathete...

Multiple interventional radiology techniques are available for percutaneous ablation of bone tumors: alcohol, laser, radiofrequency, microwave, ultrasound, and cryogenic ablation. Several indications have already been validated, including radiofrequency ablation of osteoid osteoma and bone metastases, with results superior to conventional treatment. More indications should be added over the com...

Radiofrequency ablation using a percutaneous catheter-based approach is widely used to treat supraventricular arrhythmias. Atrial fibrillation frequently arises from an abnormal focus at or near the junction of the pulmonary veins and the left atrium, thus leading to the feasibility of more focused ablation techniques directed at these structures. Catheter-based ablation, using both radiofreque...

Background: Radiofrequency ablation has been reported to be effective and safe in reducing benign thyroid volume nodules. Most studies carried out so far were performed on a limited number of large nodules and often a subset of them required more than one single treatment. Case report: We describe the case of 82-year-old woman with a very large volume thyroid nodule treated with a single sessio...

Radiofrequency Catheter Ablation. Radiofrequency catheter ablation techniques are becoming increasingly accepted as the therapy of choice for selected patients with symptomatic arrhythmias. The ability to titrate the power output using radiofrequency current has allowed these ablative techniques to be applied safely in a variety of arrhythmias. In many institutions, radiofrequency catheter abla...

OBJECTIVE Endovenous techniques are, at present, the recommended choice for truncal vein treatment. However, the thermal techniques require tumescent anaesthesia, which can be uncomfortable during administration. Non-tumescent, non-thermal techniques would, therefore, have potential benefits. This randomised controlled trial is being carried out to compare the degree of pain that patients exper...
