BACKGROUND Primary or metastatic osseous and soft tissue lesions can be treated by ablation techniques. METHODS These techniques are classified into chemical ablation (including ethanol or acetic acid injection) and thermal ablation (including laser, radiofrequency, microwave, cryoablation, radiofrequency ionisation and MR-guided HIFU). Ablation can be performed either alone or in combination...

OBJECTIVE Currently radiofrequency and cryoballoon ablations are the two standard ablation systems used for catheter ablation of atrial fibrillation; however, there is no universal consensus on which ablation is the optimal choice. We therefore sought to undertake a meta-analysis with special emphases on comparing the efficacy and safety between cryoballoon and radiofrequency ablations by synth...

Approximately 25% of all oral cavity carcinomas involve the lips, and the primary management of these lesions is complete surgical resection. Loss of tissue in the lips after resection is treated with a variety of techniques, depending on the extension and location of the defect. Here we review highly accepted techniques of lip reconstruction and some of new trials with significant clinical ...

The aim of the study was to evaluate the feasibility, safety, and efficacy of computed tomography (CT)-guided radiofrequency (RF) ablation combined with transcatheter arterial embolization (TAE) to treat large (≥10 cm) hepatic hemangiomas. We retrospectively reviewed our sequential experience with 15 large hepatic hemangiomas in 15 patients. The mean diameter of the 15 hemangiomas was 13.0 ± 2....

INTRODUCTION No prior studies have quantitatively analyzed the characteristics of bipolar or unipolar electrograms that may be helpful in identifying successful ostial ablation sites in patients with atrial fibrillation undergoing segmental pulmonary vein isolation. METHODS AND RESULTS The characteristics of bipolar and unipolar electrograms recorded at 185 successful and 120 unsuccessful ost...

lower extremity venous varicosis is a very prevalent disease. approximately 15 - 25 percent of the general population suffer from some degree of this disease. in recent years many new and innovative treatments have been developed for the disease and nowadays customary treatments ( saphenous strapping and phlebotomy) are nearly obsolete. these new treatments include laser ablation, radio frequen...

the imaging of hepatocellular carcinoma (hcc) is challenging and plays a crucial role in the diagnosis and staging of the disease. a variety of imaging modalities, such as ultrasound, computed tomography (ct), magnetic resonance imaging (mri) and nuclear medicine are currently used in evaluating patients with hcc. although the best option for the treatment of these cases is hepatic resection or...

background: posterior urethral valve presenting in adulthood is uncommon. this can be an unusual cause of primary male infertility as a result of abnormalities in sexual function. case presentation: this report describes a 40 year old man who presented to us on account of inability to impregnate his wife after 2 years of marriage. history revealed poor stream of urine since childhood and passag...

Tumor ablation by thermal, chemical and radiological sources has received substantial attention for the treatment of many localized malignancies. The primary goal of most ablation procedures is to eradicate all viable malignant cells within a designated target volume through the application of energy or chemicals. Methods such as radiotherapy, chemical and biological ablation, photodynamic ther...

Role of AF Termination: Is There Any Difference Between Direct to Sinus Rhythm Versus Via Atrial Tachycardia? During catheter ablation of persistent atrial fibrillation (AF), the arrhythmia often organizes into a regular atrial tachyarrhythmia (AT) or directly terminates to sinus rhythm (SR). The termination of AF during ablation may be associated with higher long-term maintenance of SR, and ha...
