Filter by:Low back pain is one of the most common musculoskeletal disorders affects individuals at least one during lifetime. Chronic low back pain (CLBP) lasts more than 3 months and decreases quality of life and causes work loss all over the world. Most common causes of Chronic Low back pain (CLBP) are lumbar disc herniation and/or degeneration, degenerative facet joints and sacroiliac joint pathologies, However, superior cluneal nerve (SCN) entrapment is another cause of CLBP that is ignored. It was reported that Superior cluneal nerve entrapment prevalence is % 1,6 - % 14 in CLBP patients. The Cluneal Nerves originate from the cutaneous branches of the dorsal ramus at T11-L4 and SCN innervates the skin of the upper part of the gluteal region. The nerves pass over the iliac crest through a tunnel formed by the thoracolumbar fascia and the upper edge of the iliac crest, that is the entrapment area. There are methods such as nerve blocks, neuromodulations and surgery in resistant cases. However, SCN entrapment is an overlooked diagnosis that should be considered in differential diagnosis. Recently, radiofrequency ablation (RFA) of the SCN was performed under fluoroscopic guidance, total of 78% of patients reported nearly full analgesia for an average of 3 months. Although ultrasound-guided imaging and blocking of SCN is well described, there was not enough study that shows the effectiveness of ultrasound-guided SCN RFA and compares it to conventional physical therapy (CPT) in the treatment of CLBP.
Continuous radiofrequency ablation (CRF) is the effective management for cervical facet joint pain but related with neuropathic symptoms in post-radiofrequency period. Additionally, pulse radiofrequency ablation (PRF) provides relief of neuropathic symptoms. However, the effect of CRF followed by PRF has yet to be validated
This study aims to analyse retrospectively the feasibility, the safety, and the efficiency, of biliary or digestive protection with room air interposition for thermal ablation of central liver tumors with high iatrogenic risk. Thermal ablation is a mini-invasive and curative treatement of liver tumors. However, it requires to be carefull about surrunding organs, such as digestive structures or central biliary tree, which can be injured if not insulated. The technique of gas interposition to protect adjacent gut is already known and validated with carbonic gas. Nevertheless, resorption of this gas is very fast, making its use tricky to keep a correct insulation during the whole thermal ablation process. Room air interposition is easy to use and can offer a slow resorption speed. Furthermore no datas are available concerning the use of room air whatever the organ protected, and the protection of central biliary tree whatever the gas used.
Knee osteoarthritis is a disease that increases in frequency with age and decreases the quality of life and physical activity by leading to a decrease in pain and joint range of motion. Basically, the articular cartilage is affected and clinically pain, joint stiffness, crepitation and effusion are seen. In imaging techniques applied with weight-bearing, varying degrees of joint narrowing are observed, although it is more common in the medial. Treatment options include conservative approaches such as weight loss, physical therapy, analgesics, or invasive approaches such as intra-articular injections, peripheral nerve blocks, joint-sparing surgery or total knee replacement. Surgical operation should be considered in the treatment when conservative treatments are insufficient. However, the advanced age of this patient group and the large number of comorbidities reduce the possibility of surgical operation. Although treatment cannot be cured in knee osteoarthritis, the aim of the treatment is to decrease the pain, increase the patient's quality of life and physical capacity, and slow down the progression of the disease. Although the radiofrequency ablation (RFA) technique has been used since the 1970s, the first application area was trigeminal neuralgia. Later, its use in neck and back pain became widespread, but the first randomized controlled study on its use in knee osteoarthritis was Choi et al. Made by in 2011. The purpose of radiofrequency ablation applied to the genicular nerves that receive the sensation of the knee joint capsule is to prevent sensory transmission and reduce the sensation of pain by creating axonal damage to these nerves. Since the use of RFA in knee osteoarthritis is relatively new, studies on the development of the technique continue. Fluoroscopy device or ultrasonography can be used as imaging method to show target nerves or to place the RFA electrode in the correct localization. The investigators hypothesis; based on the more prominent medial involvement in knee osteoarthritis, the conventional RFA procedure applied to the 3 genicular nerves (SMGN, IMGN, SLGN) is not superior to the RFA procedure applied to the medial SMGN and IMGN branches.
Contrast-enhanced ultrasonography (CEUS)-CT/MRI fusion imaging substantially improved the visibility of small tumors that were inconspicuous on both US and US-CT/MRI fusion imaging, contributing to successful percutaneous radiofrequency ablation.
In recent years, radiofrequency ablation has gradually become a first-line treatment for patients with atrial fibrillation. Radiofrequency ablation is an invasive procedure that lasts several hours, patients can experience varying degrees of discomfort and pain despite the use of analgesics. Mindfulness meditation requires the trainer to focus on breathing during the training process, while being non-critical and consciously observing various sensations on the body. It has a good effect in reducing pain, fatigue, negative emotions and strengthening coping with stressful events. With the rapid development of science and technology, meditation is no longer confined to traditional forms. The meditation method with the help of mobile communication technology and brain-computer interface technology can improve efficiency and convenience, and is more personalized. It has been recognized in many studies. The brain-computer interface is to establish a channel between the human brain and the computer that does not rely on conventional brain information output. Using techniques such as electroencephalogram, the spontaneous biopotential of the brain is amplified and recorded from the scalp. This study aims to explore the impact of mindfulness meditation with devices based on brain-computer interface technology on patients undergoing radiofrequency ablation of atrial fibrillation. In order to improve the negative experience of patients during ablation, ensure the safety of patients during ablation, promote postoperative recovery, and increase satisfaction. The pain intensity, fatigue level, anxiety and depression of the meditation group and the control group were compared by the scale. Record relevant vital signs and adverse events. The investigators hypothesized that the pain, fatigue, anxiety and depression of the meditation group would be lower than those of the control group.
This study is a safety and feasibility study to determine if ultrasound guided radiofrequency ablation of parotid Warthin's tumor under local anesthesia is a safe and effective procedure compared to Parotidectomy while using less resources.
The rationale of the study is to explore the safety and efficacy of endoluminal radiofrequency ablation prior metal stent insertion in patiens with malignant biliary stenosis.
Chronic neck pain is a common disorder for spine specialists. Radiofrequency ablation of medial branches has been proven effective in selected patients for relieving pain. A newer radiofrequency ablation cannula has been developed (multi-tined), allowing perpendicular access. It is proposed as an alternative to the more technically challenging traditional approach. This study aims to compared the technical and clinical aspects of both techniques.
