AIM To compare 5-year survival of patients with a single hepatocellular carcinoma≤3 cm randomly assigned to receive percutaneous ethanol injection or radiofrequency ablation. PATIENTS AND METHODS A total of 285 patients (192 males, mean age 70 years), with a single hepatocellular carcinoma (mean diameter 2.2 cm) were randomly assigned to receive percutaneous ethanol injection (n=143) or radio...

background: energy deficit is a common and serious problem in pediatric intensive care units. parenteral nutrition, either alone or in combination with enteral nutrition, can improve nutrient delivery in critically ill patients by preventing or correcting the energy deficit and improving the outcomes. intralipid 10% and 20% are lipid emulsions, widely used in parenteral nutrition. despite sever...

av-node modification by catheter rf energy delivery is treatment of choice in the symptomatic patients with avnrt. this study included 30 patients with avnrt (19 women, 11 men). we did slow pathway ablation in 29 cases successfully. maximum effective energy delivery was 40 watts for 40 msec. 1:1 av conduction increased from 290±40 msec before ablation to 340±65 msec after ablation. also av-node...

BACKGROUND/AIMS Radiofrequency ablation (RFA) is one of the most frequently applied curative treatments in patients with a single small hepatocellular carcinoma (HCC). However, the clinical significance of and risk factors for early massive recurrence after RFA-a dreadful event limiting further curative treatment-have not been fully evaluated. METHODS In total, 438 patients with a single HCC ...

Purpose: To investigate the efficacy of a new algorithm to increase the volume of tissue ablation via gradual ramp-up of power using an internally cooled electrode for ablating hepatomas 3 cm or less. Materials and Methods: 44 patients with 62 hepatomas were treated from March 4, 2004 to May 24, 2009. Ablation with a gradual ramp-up of power was performed using a single needle with an internall...

Among rate control strategies for atrial fibrillation is atrioventricular junction ablation with ventricular pacing. Concerns about the long term safety of this procedure emerge as studies report deleterious effects of right ventricular pacing. A cohort of patients having undergone atrioventricular node ablation and right ventricular pacing was retrospectively studied. After 5 years of follow-u...

INTRODUCTION There is emerging evidence for clinical superiority of catheter ablation over rate and rhythm control strategies in paroxysmal atrial fibrillation (PAF). The objective of this study was to compare costs related to medical therapy versus catheter ablation for PAF in Ontario (Canada). METHODS Costs related to medical therapy in the analysis included the cost of anticoagulation, rat...

THE PURPOSE OF THE STUDY Radiofrequency (RF) catheter ablation represents an important advance in the management of children with cardiac arrhythmias and has rapidly become the standard and effective line of therapy for supraventricular tachycardias (SVTs) in pediatrics. The purpose of this study was to evaluate the intermediate term follow up results of radiofrequency catheter ablation in trea...

Recent advances in techniques of imaging and ablation have led to the application of several minimally invasive modalities, such as radiofrequency ablation (RFA) with a success rate varying from 79 to 96% and a serious complication rate of 1 to 4% in the treatment of small renal tumors. The authors report on the case of a 67-year-old patient with a radiofrequency ablation complication, stenosis...
