27 Hepatocellular carcinoma (HCC) is the 3 leading cause of cancer-related death 28 worldwide, and the incidence of HCC is rising in the United States. Patients with cirrhosis of the 29 liver and viral hepatitis are at the highest risk of developing HCC. The diagnosis of HCC can be 30 made radiographically, with multiphase contrast-enhanced imaging; however, many lesions 31 require biopsy for d...

RATIONALE Postliver transplant periampullary carcinoma is an extremely uncommon disease. PATIENT CONCERNS Cutaneous jaundice in a patient who had received a liver transplant 4 years earlier. DIAGNOSIS Periampullary carcinoma. INTERVENTIONS Radiofrequency ablation plus fully covered self-expanding metal stents (FCSEMS). OUTCOMES The treatment of malignant neoplasm of the ampulla of Vater...

BACKGROUND Treatment of maternal tachyarrhythmias in pregnancy is a major clinical issue. Pharmacological treatment raises important concerns regarding partial efficacy and side effects. Radiofrequency ablation of arrhythmogenic substrate has rarely been performed during pregnancy because of the fetal risks related to x-ray exposure and potential fetomaternal procedural complications. CASES T...

Introduction: The standard treatment for symptomatic primary hyperparathyroidism due to parathyroid adenoma is surgery, but in patients who are not good candidates for surgery, other treatment modalities including ethanol ablation, laser ablation, ultrasound wave ablation, and radiofrequency ablation are used. We describe a patient with multiple medical problems and a parathyroid adenoma who wa...

BACKGROUND Ventricular tachycardia (VT) is a significant complication of myocardial infarction. Radiofrequency ablation for postinfarct VT is reserved for drug refractory VT or VT storms. Our hypothesis is that radiofrequency ablation in the early postinfarct period could abolish or diminish late recurrences of VT. METHODS AND RESULTS Myocardial infarct was induced by balloon occlusion of the...

Percutenous catheter ablation of the accessory pathway in Wolff-Parkinson-White syndrome is a highly successful mode of therapy. Sudden cardiac arrest survivors associated with WPW syndrome should undergo radiofrequency catheter ablation. WPW syndrome associated with familial atrial fibrillation is a very rare condition. Herein, we describe a case who presented with sudden cardiac arrest second...

Effective local ablation of large tumors with radiofrequency has been made possible by recent advancements. Tumor ablation with radiofrequency has been described mainly in the liver, but also recently in the kidney, adrenal gland, lung, and breast. A rapidly growing splenic metastasis from renal cell carcinoma was effectively treated percutaneously, with US guidance. Focal splenic disease may n...
