OBJECTIVE: Osteoblastoma (OB) is a painful, rare, benign bone tumour usually observed in young populations, and this condition involves the spine in up to one-third of cases. We sought to focus on the minimally invasive treatment of spinal OB with radiofrequency ablation (RFA) under computed tomography (CT) guidance. When performed near the spinal cord, surgery can lead to instability of the spine, sometimes requiring additional interventions to stabilise the segments involved, and can cause the precocious onset of arthrosis or other degenerative diseases...

Introduction Irreversible electroporation (IRE) is a non-thermal minimally invasive technique to treat small renal masses (SRM). Prior work has demonstrated greater narcotic requirements after radiofrequency ablation (RFA) for tumors closer to body-wall musculature. We hypothesized that pain after IRE is not dependent on tumor location due to the athermal mechanistic action. Methods Retrospective review of 50 consecutive percutaneous IRE and RFA cases was performed from 2013 to 2014. Eight patients were excluded from analysis due to incomplete anesthesia record and/or multiple ablations per session leaving 21 patients in each group...

BACKGROUND: Air embolus penetrating into heart chamber as a complication during percutaneous radiofrequency catheter ablation has been infrequently reported. CASE PRESENTATION: A 55-year-old man with dextrocardia who suffered from abdominal pain was suspected to have multiple arterial thromboembolisms, which might have originated from left atrium thrombosis since he had atrial fibrillation. He received oral anticoagulant therapy and catheter ablation of the arrhythmia...

Pregnancy is known to aggravate pre-existing chronic painful conditions. Trigeminal neuralgia (TN), albeit a disease of elderly may afflict pregnant females which can further complicate its management. Teratogenic effects of the commonly used drugs on the developing fetus limit pharmacological treatment. Moreover safety of commonly performed interventional therapies is marred by their inherent fetomaternal effects and more importantly the risk of radiation effects on fetus due to the use of fluoroscopy. This rare coexistence of TN in pregnancy is never reported before...

We present a case of a 76-year-old man with right upper quadrant abdominal pain and weight loss, who was found to have an intraductal papillary neoplasm of the bile duct (IPNB) of the pancreaticobiliary subtype, deemed curatively resectable. The patient declined surgery and opted for endoscopic therapy. He underwent two sessions of endoscopic retrograde cholangiopancreatography (ERCP)-guided radiofrequency ablation (RFA). Ten months later, no evidence of recurrence was identified on repeat ERCP. To our knowledge, this is the first reported case of successful use of RFA as a primary treatment modality for resectable IPNB...

BACKGROUND: In thyroid gland, radiofrequency ablation (RFA) has been applied to both recurrent cancers and benign nodules, although, according to the American Thyroid Association (ATA) and the Korean Society of Thyroid Radiology (KSThR) guidelines, surgery is the first-line treatment for follicular neoplasm. However, it has been argued that follicular neoplasm with lower risk of malignancy can be managed by close follow-up. In this study, we evaluated the effectiveness of RFA of small follicular neoplasms, examining reductions in volume and related clinical problems, and making observations over long-term follow-up...

BACKGROUND: Patients with supraventricular tachycardia (SVT) and patients with coronary artery disease (CAD) often present with similar symptoms (chest pain, shortness of breath), similar electrocardiographic changes and elevated high-sensitivity troponin (cTn). It is not clear whether troponin reflects critical CAD or is elevated due to other causes in patients presenting with SVT. The aim of this study was to assess the role of elevated troponin in patients presenting with SVT. METHODS: Patients undergoing radiofrequency ablation (RFA) for SVT and simultaneous coronary angiography at the Heart Centre Lucerne, Switzerland between January 2010 and October 2014 were included in this analysis...

Radiofrequency (RF) ablation is the first-line management of cavo-tricuspid isthmus dependent atrial flutter. It has been performed with 95% success rate. Adverse events are very rare. We report the first case of acute severe mitral regurgitation (MR) and complete heart block developed after successful atrial flutter ablation. A 62-year-old female with mild MR presented with palpitations. Surface electrocardiogram was suggestive of isthmus dependent atrial flutter. A duodecapolar mapping catheter showed an atrial flutter with cycle length of 280 ms...

BACKGROUND: Morton's neuroma is a common cause of forefoot pain. Outcomes of conservative therapy are mixed and many patients undergo operative intervention. Radiofrequency ablation has recently gained favor as a treatment option, although the optimal regime is unknown. This study investigates the effectiveness of 2 versus 3 cycles of radiofrequency ablation for the treatment of Morton's neuroma. METHODS: We surveyed a cohort of patients with Morton's neuroma who had progressed to radiofrequency ablation after failed conservative treatment...

Objectives.:  Percutaneous radiofrequency ablation (RFA) of the gasserian ganglion through the foramen ovale and the glossopharyngeal nerve at the jugular foramen is a classical approach to treating trigeminal neuralgia (TN) and glossopharyngeal neuralgia (GPN), respectively. However, it can be technically challenging with serious complications. We have thus developed a novel technique utilizing C-arm and computerized tomography (CT) guidance to block TN and GPN. Our goals were to describe a three-dimensional image-based technique to improve patient comfort and to decrease procedural time associated with needle guidance...

Asthma is a chronic airway disease in which the pathological mechanisms are reversible airway obstruction, bronchial hyper reactivity, and constriction of the lower airways. Supraventricular tachycardia (SVT) is a common arrhythmia which originates above the bundle of His and causing heart rates exceeding 150 beats/min. SVT patients present with palpitation, chest pain, chest discomfort, dyspnea, hyperventilation, and lightheadedness, occasionally. Besides, extraordinary presentations of SVT are available in literature...

BACKGROUND: Approximately 24% of adults in the United States have visible varicose veins, and an estimated 6% have evidence of advanced chronic venous disease. The majority of individuals with varicose veins seek treatment because of symptoms, such as aching, throbbing, fatigue, pruritus, ankle swelling, and tenderness, rather than cosmetic reasons. Furthermore, varicose veins are a manifestation of chronic venous insufficiency, which can progress to leg pain, leg edema, chronic skin changes, and nonhealing ulcers...

Primary malignant melanoma of the gastrointestinal tract is extremely rare. A 35-year-old man presented with complaints of abdominal pain and weight loss. Contrast enhanced computed tomography showed a large mass involving the duodenum and the superior mesenteric vessels. Upper gastrointestinal endoscopy demonstrated a large, friable mass along the duodenal wall and biopsy was suggestive of malignant melanoma. A detailed physical examination and whole body imaging (positron emission tomography and computed tomography) did not reveal any other lesion...
