BACKGROUND: Radiofrequency therapy (RFT) generates molecular motion, and produces heat and electromagnetic effects on tissues, which attenuate pain sensation and thereby relieve pain. This study was to observe the altering trend of physiological parameters after RFT for chronic cervical or lumbar pain. METHODS: This study recruited 66 patients with chronic cervical or lumbar pain, and recorded their physiological parameters before and after RFT by using heart rate variability (HRV) and photoplethysmography (PPG) to explore the feasibility of RFT efficacy assessment...

Radiofrequency (RF) parathyroid ablation is a noninvasive treatment for hyperparathyroidism in dogs. There are no published data assessing factors associated with RF parathyroid ablation success or failure in order to guide patient selection and improve outcome. The purpose of this retrospective analytical study was to determine whether imaging findings, biochemical data, or concurrent diseases were associated with RF heat ablation treatment failure. For inclusion in the study, dogs must have had a clinical diagnosis of primary hyperparathyroidism, undergone cervical ultrasound and RF ablation of abnormal parathyroid tissue, and must have had at least 3 months of follow-up information available following the date of ultrasound-guided parathyroid ablation...

PURPOSE: Increased signal-to-noise ratio and blood oxygenation level-dependent sensitivity at 7 Tesla (T) have the potential to enable high-resolution imaging of the human cervical spinal cord and brainstem. We propose a new two-panel radiofrequency coil design for these regions to fully exploit the advantages of ultra-high field. METHODS: A two-panel array, containing four transmit/receive and 18 receive-only elements fully encircling the head and neck, was constructed following simulations demonstrating the B1+ and specific absorption rate (SAR) benefits of two-panel over one-panel arrays...

PURPOSE: Radiofrequency ablation has been advocated as an alternative to radioiodine and/or surgery for the treatment of autonomously functioning benign thyroid nodules. However, only a few studies have measured radiofrequency ablation efficacy on autonomously functioning benign thyroid nodules. The aim of this work was to evaluate the 12-month efficacy of a single session of radiofrequency ablation (performed with the moving shot technique) on solitary autonomously functioning benign thyroid nodules...

Palliative cervical cordotomy can be performed via percutaneous radiofrequency ablation of the lateral C1-2 spinothalamic tract. This rare procedure can be safe, effective, and advantageous in mitigating medically intractable unilateral extremity pain for selected patients with end-stage cancer. This report reviews the indications, techniques, risks, and potential benefits of cordotomy. We describe our recent experience treating 3 patients with CT-guided C1-2 cordotomy and provide the first characterization of spinal cord diffusion MR imaging changes associated with successful cordotomy...

BACKGROUND AND OBJECTIVES: Novel multitined cannulae constitute an attractive option for ultrasound-guided radiofrequency neurotomy of cervical medial branches. The deployment tines increase the cannula's active area, thus altering its lesion size. Despite their theoretical benefits, multitined cannulae have not been assessed. In this bench study, we sought to investigate the lesions produced by a standard 18-gauge and 2 commercially available multitined deployment cannulae. We created ex vivo models to evaluate lesion morphology at a periosteal interface using approach angles likely to be encountered during an ultrasound-guided technique...

The cervical facet joints, also called the zygapophyseal joints, are a potential source of neck pain (cervical facet joint pain). The cervical facet joints are innervated by the cervical medial branches (CMBs) of the cervical segmental nerves. Cervical facet joint pain has been shown to respond to multisegmental radiofrequency denervation of the cervical medial branches. This procedure is performed under fluoroscopic guidance. Currently, three approaches are described and used. Those three techniques of radiofrequency treatment of the CMBs, classified on the base of the needle trajectory toward the anatomical planes, are as follows: the posterolateral technique, the posterior technique, and the lateral technique...

Transforaminal Epidural steroid injections (TFESI) have been widely adopted to alleviate and control radicular pain in accord with current guidelines. However, sometimes repeated steroid injections have adverse effects, and thus, this prospective randomized trial was undertaken to compare the effectivenesses of pulsed radiofrequency (PRF) administered to a targeted dorsal root ganglion (DRG) and TFESI for the treatment of radicular pain due to disc herniation. Subjects were recruited when first proved unsuccessful (defined as a score of > 4 on a visual analogue scale (VAS; 0-10 mm) and of > 30% according to the Oswestry Disability Index (ODI) or the Neck Disability Index (NDI))...

Bing Liu, Liangjun Cheng, Hao Ming, Chang Zhong
OBJECTIVE: Radiofrequency (RF) coblation operates at low temperatures (40-70°C) and allows for ablation, hemostasis, and aspiration, in addition to the lesion excision; thermal damage to the surrounding tissues is thus minimized. Herein, we evaluated the benefit of low-temperature RF coblation treatment of the early-stage glottic cancer. The main aim of the study was to evaluate the feasibility, complications, and efficacy of low-temperature RF coblation as a treatment modality for the early-stage glottic cancer...

BACKGROUND AND AIMS: The cervical inlet patch (CIP) is an area of heterotopic gastric mucosa at the proximal esophagus, which can secrete both acid and mucus. Attributable symptoms include chronic globus sensation and sore throat. Previous studies have demonstrated improvement in symptoms after ablation using argon plasma coagulation. Our aim was to assess a through-the-scope radiofrequency ablation (RFA) catheter for ablation of symptomatic CIP. METHODS: Ten patients with endoscopically and histologically proven CIP and symptoms of globus or sore throat were included in the study...

We report 2 cases of successful treatment of neck and back pain with bipolar radiofrequency ablation (RFA) of the cervical and lumbar facet joints in patients with an automatic implantable cardioverter defibrillator (AICD).Two patients with complex cardiac histories and AICD devices were treated with bipolar RFA of the facet joints. One presented with axial neck pain and the other with axial back pain. The histories and physical examinations were consistent with facetogenic pain. Diagnostic medial branch block resulted in more than 70% pain relief lasting for several days, allowing patients to perform routine daily activities without significant pain...

A 28-year-old female consulted in 1994 for a left thyroid nodule known for two years with documented progression. Left lobe resection was performed initially followed by total thyroidectomy without lymph node dissection in September 1994. Pathological examination concluded on unilateral 10 × 40 mm medullary thyroid carcinoma (MTC). RET mutation was negative. Basal and pentagastrin-stimulated CT levels had been normal from 1994 to 2008 when her CT level was found to be elevated at 33 ng/L and increased subsequently to 111 ng/L in 2010...

Diagnostic facet joint nerve blocks have been utilized in the diagnosis of cervical facet joint pain in patients without disk herniation or radicular pain due to a lack of reliable noninvasive diagnostic measures. Therapeutic interventions include intra-articular injections, facet joint nerve blocks and radiofrequency neurotomy. The diagnostic accuracy and effectiveness of facet joint interventions have been assessed in multiple diagnostic accuracy studies, randomized controlled trials (RCTs), and systematic reviews in managing chronic neck pain...

Radiofrequency denervation of the cervical medial branches is a possible treatment for chronic cervical facet pain syndrome when conservative management has failed. According to the literature, complications after radiofrequency denervation of the cervical medial branches are rare. We report a case of possible phrenic nerve injury after ipsilateral radiofrequency denervation of the cervical medial branches following a posterolateral approach.

Complex regional pain syndrome (CRPS) following injury or nerve damage, as its name signifies, is a challenging entity, and its successful management requires a multidisciplinary approach. It not only manifests as severe pain, but also gives rise to functional disability, lack of sleep, lack of enjoyment of life and poor quality of life. Various pain interventional techniques have been described in the literature for the management of CRPS ranging from sympathetic blocks to spinal cord stimulator. A 34-year-old liver transplant donor, who developed position-induced right upper limb neuropathic pain suggestive of CRPS type II was managed initially with medications and later with stellate ganglion block under fluoroscopic guidance at cervical C7 position...
