181. Retrospective Study of the Results of Cooled Radiofrequency for Genicular Nerves Neurotomy in 40 Consecutive Patients With Osteoarthritis of the Knee and Painful Knee Arthroplasty

by the National Library of Medicine related topics: related topics: Groups and Cohorts Go to Intervention Details: Procedure: cooled radiofrequency ablation of genicular nerves Cooled RF consists of creating an injury in the nerve trough a high frequency flow. Unlike conventional RF, in cooled RF through a closed circuit where intravenous flows, we can create an injury for a longer period of time, at a lower temperature (standard RFA 90º C, cooled RFA 60º C) and within an area 8 times larger.

184. Therapy of Pancreatic Neuroendocrine Tumors: Fine Needle Intervention including Ethanol and Radiofrequency Ablation Full Text available with Trip Pro

Therapy of Pancreatic Neuroendocrine Tumors: Fine Needle Intervention including Ethanol and Radiofrequency Ablation Pancreatic neuroendocrine tumors (PNETs) are increasingly being detected, though usually as incidental findings. Majority of the PNETs are non-functional and surgical resection is the standard of care for most of them. However, in patients with small PNETs localized within the pancreas, who are unfit or unwilling for surgery, alternate methods of treatment are needed. Direct (...) methods of ablation of PNETs, using either ethanol injection or radiofrequency ablation (RFA), are emerging as effective methods. The limited literature available as case reports or case series on endoscopic ultrasound (EUS)-guided local ablation using either ethanol or RFA has demonstrated safety and efficacy along with short- to medium-term sustained relief. Long-term benefits with these local ablative therapies are awaited. Comparative studies are needed to show which of these two competing

188. Hyperspectral imaging for label-free in vivo identification of myocardial scars and sites of radiofrequency ablation lesions. Full Text available with Trip Pro

Hyperspectral imaging for label-free in vivo identification of myocardial scars and sites of radiofrequency ablation lesions. Treatment of cardiac arrhythmias often involves ablating viable muscle tissue within or near islands of scarred myocardium. Yet, today there are limited means by which the boundaries of such scars can be visualized during surgery and distinguished from the sites of acute injury caused by radiofrequency (RF) ablation.We sought to explore a hyperspectral imaging (HSI (...) ) methodology to delineate and distinguish scar tissue from tissue injury caused by RF ablation.RF ablation of the ventricular surface of live rats that underwent thoracotomy was followed by a 2-month animal recovery period. During a second surgery, new RF lesions were placed next to the scarred tissue from the previous ablation procedure. The myocardial infarction model was used as an alternative way to create scar tissue.Excitation-emission matrices acquired from the sites of RF lesions, scar region

Comparison of umbilical cord occlusion methods: radiofrequency ablation versus laser photocoagulation. To compare outcomes between 2 umbilical cord occlusion (UCO) methods: radiofrequency ablation (RFA) versus fetoscopic-guided laser photocoagulation.Retrospective study of all monochorionic diamniotic multiple gestations that underwent UCO with RFA (preferred after 2014) or laser (preferred before 2014). In bivariate analysis, patients treated with RFA were compared with laser. Risk factors (...) for intrauterine fetal demise (IUFD) and 30-day survival of the co-twin were identified, and multiple logistic models were fitted to examine whether the UCO method was associated with these outcomes.Of 60 UCO cases, 18 (30%) underwent RFA and 42 (70%) underwent laser surgery. The RFA method was associated with co-twin IUFD after surgery (6/18 [33.3%] vs 1/42 [2.4%], P = 0.0021). In logistic regression models, patients who underwent RFA were more likely than patients who underwent laser to have an IUFD

This study aimed to compare the effectiveness and safety of coblation annuloplasty and radiofrequency thermocoagulation for lumbar discogenic pain.Patients who suffered from lumbar discogenic pain and underwent coblation annuloplasty and radiofrequency thermocoagulation surgery were included. A questionnaire, including the visual analo scale (VAS), MacNab criteria, pain relief rate (...) , and any complications due to surgery, was completed by the patients with the help of a trained volunteer who was blinded to the study. Data were collected at 1 week, and 1, 3, 6, and 12 months after surgery. Significant pain relief was defined as postoperative pain relief ≥50% compared with the preoperative state. Any complications during or after surgery were also recorded.A total of 122 patients were included; 37 patients were lost in the follow-up and 85 were evaluated. Among these, 45 patients
