NCT ID: NCT06240000 Completed - Low Back Pain Clinical Trials

Radiofrequency Ablation of the Superior Cluneal Nerve

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06033456 Recruiting - Mastectomy Clinical Trials

Combining Stellate Ganglion and T2 and T3 Radiofrequency Ablation on Post-mastectomy Complex Regional Pain Syndrome

Start date: October 7, 2023
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate the efficacy of the combination of Ultra Sound (US) guided radiofrequency stellate ganglion block (SGB) and radiofrequency Thoracic Paravertebral block (TPVB) comparing to US-guided SGB or TPVB alone on the post-mastectomy pain syndrome (PMPS).

NCT ID: NCT06003218 Recruiting - Liver Cancer Clinical Trials

Dexmedetomidine-esketamine for Percutaneous Radiofrequency Liver Ablation

Start date: October 16, 2023
Phase: N/A
Study type: Interventional

Percutaneous radiofrequency ablation is a commonly treatment for patients with liver cancer that cannot be surgically resected. During the procedure, patients need to keep awake and cooperate with the procedure, including deep breath and hold breath. However, intolerable pain generated during puncture and radiofrequency heating may cause body movements and interfere the procedure. Oxycodone is frequently used for analgesia but still insufficient. A recent study showed that dexmedetomidine-esketamine combination improves analgesia without increasing adverse events. After stopping infusion, the analgesic/sleep-promoting effects of dexmedetomidine-esketamine seemed to last for up to 24 hours. The investigators hypothesize that dexmedetomidine-esketamine combination as a supplement to oxycodone will improve sedation and analgesia in patients undergoing radiofrequency liver ablation of the liver.

NCT ID: NCT05991856 Recruiting - Clinical trials for Radiofrequency Ablation

Multifaceted Comparison of Ultrasound-guided Ablation and Laparoscopic Adrenalectomy for Aldosterone-producing Adenoma

Start date: January 1, 2020
Phase:
Study type: Observational

The purpose of this study is to retrospectively and prospectively analyze the efficacy and safety of ultrasound-guided radiofrequency ablation and laparoscopic adrenalectomy in the treatment of aldosterone-producing adenoma (APA). It is planned to retrospectively collect 30 patients with adrenal radiofrequency ablation for APA and 15 patients with age - and sex-matched laparoscopic adrenalectomy for APA in our hospital from January 2020 to June 2024, and continue to follow up for 3 years.

NCT ID: NCT05916846 Recruiting - Pancreatic Cyst Clinical Trials

Endoscopic Ultrasound-guided Radiofrequency Ablation of Pancreatic Cysts (ERASE)

ERASE
Start date: April 24, 2023
Phase: N/A
Study type: Interventional

A single-center study to determine the safety and efficacy of EUS-guided radiofrequency ablation (RFA) of pancreatic cystic neoplasms (PCNs). Patients will be recruited sequentially to undergo RFA followed by standard surveillance. The study will recruit patients with pancreatic cystic lesions (PCLs) who are at high risk for surgical resection. Patients enrolled in the study will be followed up for 3-years after EUS-guided RFA.

NCT ID: NCT05818176 Recruiting - Clinical trials for Radiofrequency Ablation

To Improve the Clinical Outcome of Ultrasound-guided Radiofrequency Ablation by NAVIRFA® Navigation System.

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

Ultrasonic-guided radiofrequency ablation is the most common minimally invasive treatment for liver cancer. This study will use my country's self-developed intelligent ultrasonic navigation tool (NAVIRFA® Navigation System) to assist in the puncture of the needle during ablation, to observe the operation time, Whether the needle accuracy, ablation effect and complications are different from the traditional free-hand ultrasonic guidance technology.

NCT ID: NCT05719948 Completed - Clinical trials for Radiofrequency Ablation

Combined Continuous and Pulsed Radiofrequency Ablation for Pain Relief and Their Safety in Cervical Facet Pain

Start date: October 1, 2020
Phase: N/A
Study type: Interventional

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

NCT ID: NCT05610215 Not yet recruiting - Atrial Fibrillation Clinical Trials

Concomitant Hybrid Versus Catheter Ablation for Atrial Fibrillation With Hypertrophic Cardiomyopathy

Start date: February 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to compare the rhythm control effect in hypertrophic non-obstructive patients with non-paroxysmal atrial fibrillation by either concomitant catheter endocardial and thoracoscopic epicardial ablation or catheter ablation alone. The study aims to see if concomitant hybrid ablation can more effectively achieve rhythm control effect than catheter ablation alone in non-paroxysmal atrial fibrillation patients with hypertrophic cardiomyopathy.

NCT ID: NCT05559073 Not yet recruiting - Atrial Fibrillation Clinical Trials

Outcomes of Early Referral to Radiofrequency Ablation in Symptomatic Atrial Fibrillation Patients.

Start date: October 6, 2022
Phase:
Study type: Observational

Atrial fibrillation (AF) is the most common arrhythmia among adults with increasing risk of stroke, heart failure and mortality. The EAST-AFNET 4 trial showed that rhythm control treatment (Antiarrhythmic drugs AAD or catheter ablation) was associated with a lower risk of adverse cardiovascular outcomes than usual care among patients who had recently (within one year) been diagnosed with atrial fibrillation. In phase II/III GLORIA AF registry, Early AF ablation within 3 months from initial diagnosis in a contemporary cohort of patients who were predominantly treated with non-vitamin K antagonist oral anticoagulants was associated with a survival advantage compared to medical therapy alone. Moreover, early AF ablation appeared to provide the greatest benefit compared to other treatments. The ATTEST trial was a multicenter, randomized, prospective study in patients with paroxysmal atrial fibrillation (AF) designed to assess whether radiofrequency (RF) ablation is more effective in delaying the progression to persistent AF than AADs. Patients >_65 years were significantly more likely to progress to persistent AF/AT than patients were <65 years, suggesting that early RF ablation may be an effective treatment strategy for delaying AF progression. So, we hypothesize that early AF ablation within one year after first AF diagnosis may associate with improved procedures outcomes in symptomatic AF patients.

NCT ID: NCT05500703 Recruiting - Epilepsy Clinical Trials

Brain Regions and Functional Neuronal Network Characteristics of Dexmedetomidine Analgesia

Start date: October 15, 2022
Phase: Phase 4
Study type: Interventional

Background: Dexmedetomidine (DEX) is a highly selective 2-adrenergic receptor agonist with significant analgesia affection. This study is planned to explore the brain regions and functional neuronal network involved in promoting analgesia of Dexmedetomidine. Methods: Select 12 patients with the proposed intraoperative MR-guided radiofrequency ablation of epilepsy. The subjects were randomized into the Dexmedetomidine group (DEX group) (n=6) and the Opioid group (OPI group) (n=6). DEX group: continuous intravenously administered 1.5 µg kg-1 h-1 dexmedetomidine 15min before anesthesia induction, continuous infusion for 15min after anesthesia induction, and then Intraoperative functional magnetic resonance imaging scanning was started. OPI group: the equivalent administered speed 0.9% sodium chloride was continuously pumped for 15min before anesthesia induction, then induce and intraoperative fMRI scanning started after continuous 30min infusion. The intraoperative fMIR scan results were compared and analyzed to find the unique analgesic brain regions of DEX, and the differences of the functional neuronal network of analgesia effect between the two groups.
