radiofrequency ablation pain

BACKGROUND: Given the high prevalence of chronic shoulder pain and encouraging early results of terminal sensory articular branch (TSAB) radiofrequency ablation to treat shoulder pain, research is warranted to refine the procedural technique based on updated neuroanatomical knowledge with the goal of further improving patient outcomes. OBJECTIVE: We describe an updated radiofrequency ablation protocol that accounts for varied locations of the TSABs of suprascapular, axillary, subscapular and lateral pectoral nerves within individual patients...

The aim of this study was to evaluate treatment of osteoid osteomas using bipolar radiofrequency ablation (RFA) and patients' quality of life before and after therapy. We retrospectively evaluated patients who underwent bipolar RFA of osteoid osteomas between 2001 and 2016. We assessed patients' symptoms before and after treatment (four weeks after treatment and long-term) using a questionnaire including severity and quality of pain on a 10-point scale (1 = no pain, 10 = severe pain), motion restrictions, pain-related sleep disorders, and necessary pain medication...

Chronic lumbar and back pain caused by degenerative vertebral endplates presents a challenging issue for patients and clinicians. As a new minimally invasive spinal treatment method, radiofrequency ablation of vertebral basal nerve in bone can denature the corresponding vertebral basal nerve through radiofrequency ablation of degenerative vertebral endplate. It blocks the nociceptive signal transmission of the vertebral base nerve, thereby alleviating the symptoms of low back pain caused by the degenerative vertebral endplate...

PURPOSE OF REVIEW: Surgery is a cornerstone in the management of pancreatic cancer and precancerous pancreatic lesions. However, many patients are not suitable candidates for surgery at the time of diagnosis for various reasons. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) appears to be a promising treatment option for patients who are ineligible for surgery for management of pancreatic adenocarcinoma (PDAC), and pancreatic neuroendocrine tumors (PNETs), and pancreatic cystic lesions (PCLs)...

OBJECTIVES: This study was aimed to assess the preliminary outcomes of radiofrequency ablation (RFA) using a newly developed catheter (VENISTAR) for the treatment of incompetent great saphenous veins (GSVs). METHODS: In this prospective observational study, endovenous RFA using a VENISTAR catheter was performed on 16 saphenous veins in 12 patients between August and November 2019. Patients' pre- and post-procedural data were recorded. Doppler ultrasound imaging and clinical evaluation were performed at 1 week and 1, 3, and 6 months to determine the efficacy and safety of the treatment...

Data on the use of radiofrequency (RT) to ablate a tumor mass-causing pain have not been reported. A male in his 50s, diagnosed with a pelvic relapse of rectal cancer, was admitted for pain from the left groin to the perineum. The principal findings of contrast-enhanced computed tomography (CT) revealed the presence in the pelvic area of large solid tissue infiltrating the internal obturator muscle and eroding the vertebral column of the acetabulum. Also involving the gluteal muscles.He was poorly responsive to multiple opioids...

INTRODUCTION: Laser and radiofrequency ablation are two thermal ablation methods currently widely used to treat lower limb venous insufficiency. However, very few studies have been conducted on the use of microwaves, a form of thermal ablation, for the treatment of small saphenous vein (SSV) insufficiency. This study aimed to examine the efficacy and safety of endovenous microwave ablation (EMA) for the treatment of SSV insufficiency. METHODS: The clinical data of 126 patients (126 lower limbs) with SSV insufficiency (SSV trunk reflux time ≥ 500 ms on lower limb color Doppler ultrasound) treated at the Surgery Department of The Sixth People's Hospital of Zhuji from January 2020 to June 2022 were analyzed retrospectively; 64 patients underwent EMA and 62 underwent endovenous laser ablation (EVLA)...

INTRODUCTION: Trigeminal neuralgia (TGN) poses a therapeutic challenge, particularly within the context of multiple sclerosis (MS). This study aimed to conduct a comprehensive meta-analysis and systematic review of four less-invasive treatment modalities for TGN in MS patients, namely, gamma knife radiosurgery (GKRS), glycerol rhizotomy (GR), balloon compression (BC), and radiofrequency ablation (RFA). METHODS: Single-armed meta-analyses were employed to assess the overall efficacy of each treatment, while double-armed analyses compared the efficacy between different treatment options in double-armed studies...

Post-mastectomy pain syndrome (PMPS) is a syndrome broadly applied to the development of chronic pain after surgical breast intervention (i.e., lumpectomy and mastectomy). The incidence of PMPS is likely underreported, and this has contributed to a paucity of high-level evidence related to the treatment of the aforementioned condition. A drive to reduce the burden of opioid use has led to pain management physicians trialing a variety of strategies to help patients manage PMPS. This review discusses the latest evidence behind treatment options for PMPS, exploring medications as well as interventional techniques (e...

Persistent knee pain in patients around the fifth decade of life is a frequent cause of attention in rehabilitation consultations. The most common cause of diagnosis is knee osteoarthritis, considering the existence of different degrees seen in simple radiographies. The advanced degrees present joint space reduction, osteophytosis and subchondral sclerosis; however, in the initial degrees, the findings are more subtle and sometimes nonexistent for conventional radiology. Clinical ultrasound has partly come to fill this «diagnostic gap», making it possible to detect meniscal extrusions and small osteophytes as signs of incipient osteoarthritis and to relate them as triggers of pain...

PURPOSE: Radiofrequency ablation (RFA) is an effective and safe modality for the treatment of thyroid nodules. Nodule rupture is a major complication of RFA. There is little known on the natural history of nodule rupture due to a lack of clinical experience and no consensus on its management. A comprehensive review of nodule rupture presentation, diagnosis, and management is needed. METHODS: We report a case of nodule rupture and conduct a literature review. A total of 33 patients experiencing nodule rupture after RFA were included, and their clinical presentation, management, and outcomes were collected and analyzed...

BACKGROUND: Radiofrequency ablation of genicular nerves is recommended to ameliorate the pain of osteoarthritis of the knee. However, long-term efficacy in patients with persistent pain following total knee arthroplasty remains elusive. The current study aimed to evaluate radiofrequency ablation of genicular nerves using a hybrid technique to manage severe incapacitating pain and quality of life following surgery. METHODS: This prospective, observational study included patients suffering from intractable knee pain with scores > 4 on the Numeric rating scale after 6 months of total knee arthroplasty...

BACKGROUND AND AIM: The REgistry of Selective Internal radiation therapy in AsiaNs (RESIN) was a multicenter, single-arm, prospective, observational study of 90 Y resin microspheres in patients with hepatocellular carcinoma (HCC) or metastatic colorectal cancer (mCRC) from Taiwan. RESIN is the first real-life clinical study of this therapy in an Asian cohort. Study objectives were to evaluate the safety and efficacy of 90 Y resin microspheres. METHODS: Adults with HCC or mCRC scheduled to receive SIRT with 90 Y resin microspheres were included...

BACKGROUND: To date, there is still a lack of standardized management strategies for gastric low-grade dysplasia (LGD), which is a direct neoplastic precancerous lesion and requires specifically superficial destruction. Radiofrequency ablation (RFA) is expected to be an effective method for gastric LGD, but post-RFA pain may affect patients' satisfaction and compliance. The current study aimed to evaluate the value of a submucosal injection prior to RFA (SI-RFA) for postoperative pain and treatment outcomes...

BACKGROUND: Despite the routine use of radiofrequency (RF) for the treatment of chronic pain in the lumbosacral and cervical region, there remains uncertainty on the most appropriate patient selection criteria. This study aimed to develop appropriateness criteria for RF in relation to relevant patient characteristics, considering RF ablation (RFA) for the treatment of chronic axial pain and pulsed RF (PRF) for the treatment of chronic radicular pain. METHODS: The RAND/UCLA Appropriateness Method (RUAM) was used to explore the opinions of a multidisciplinary European panel on the appropriateness of RFA and PRF for a variety of clinical scenarios...

BACKGROUND: Although nerve decompression surgery is an effective treatment for refractory occipital neuralgia (ON), a proportion of patients experience recurrence of pain and undergo reoperation. This study analyzes the incidence, risk factors, and outcomes of reoperation following primary greater occipital nerve (GON) decompression. METHODS: 215 patients who underwent 399 primary GON decompressions were prospectively enrolled. Data included patient demographics, past medical and surgical history, reoperation rates, intraoperative findings, surgical technique, and postoperative outcomes in terms of pain frequency (days/month), duration (hours/day), intensity (scale 0-10), and migraine headache index (MHI)...

OBJECTIVE: The objective of this study is to investigate safety and effectiveness of a fluoroscopy-guided high-intensity focused ultrasound (HIFU) system for thermal ablation of the lumbar medial branch nerves. METHODS: This dual center prospective cohort study enrolled 30 participants with lumbar zygapophyseal joint syndrome. Each participant previously had a positive response to either a single diagnostic analgesic block or radiofrequency ablation (RFA). The primary effectiveness outcome was individual responder rate, defined as a reduction of two points or more on the pain intensity numerical rating scale without an increase in opioid intake, or a reduction in opioid intake without an increase in pain at 6 months after the intervention...

BACKGROUND: Radiculopathy of the lower limb after acute osteoporotic vertebral fractures (OVFs) in the lower lumbar spine is uncommon in geriatric patients. Moreover, surgical intervention is generally recommended in patients who are irresponsive to conservative treatment. Determining an optimum surgical strategy is challenging considering the poor general condition of this population. Thus, herein, we established an algorithm for surgically managing this clinical scenario, hoping to provide a reference for making a surgical decision...

OBJECTIVES: Total Hip Arthroplasty (THA) may be a risky proposition in patients with comorbidities, and they may require systemic analgesics for chronic hip pain (CHP). Since traditional pain medications may not provide complete pain relief or carry prohibitive adverse effects, pulsed radiofrequency (PRF) treatment of the hip articular nerves (HAN) has been proposed for effective clinical outcomes. We determined the efficacy of PRF-HAN in improvement in CHP compared to baseline pain on conventional systemic analgesics...
