Cancer pain is most commonly classified as nociceptive (somatic or visceral) or neuropathic. Different types of pain or pain syndromes are present in all phases of cancer (early and metastatic) and are inadequately treated in 56% to 82.3% of patients. Percutaneous neurolysis and neuromodulation are feasible and reproducible, efficient (70-80% success rate) and safe (≈ 0.5% mean complication rate) palliative therapies for pain reduction in oncologic patients with refractory pain. Percutaneous neurolysis can be performed either by injection of a chemical agent (phenol or alcohol) or by application of continuous radiofrequency or cryoablation...

INTRODUCTION: Skin rejuvenation procedures have become common with sophisticated technologies with reduced downtime and related risks. Recently, microneedling has been paired with radiofrequency to create Fractional Radiofrequency Microneedling (FRFM) to induce neocollagenesis. Frequently, topical products are applied immediately after the needling. This procedure is known as percutaneous collagen induction therapy (PCIT). Postoperative topical wound care is critical for prompt rapid and safe healing, with moist wound healing deemed of primary importance for fast and correct scarring process...

Metastatic pheochromocytoma and paraganglioma (PPGL) are incurable neuroendocrine tumors. The goals of treatment include palliating symptoms and reducing tumor burden. Little is known about the use of radiofrequency ablation (RFA), cryoablation (CRYO), and percutaneous ethanol injection (PEI) to treat metastatic PPGL. We performed a retrospective study of patients age 17 years and older with metastatic PPGL who were treated with ablative therapy at Mayo Clinic, USA, between June 14, 1999 and November 14, 2017...

IntroductionPulmonary atresia, ventricular septal defect, major aorto-pulmonary collateral arteries, and pulmonary arteries hypoplasia are rare and complex congenital defects that require early interventions to relieve cyanosis and enhance the growth of native pulmonary arteries. The treatment of these patients is still controversial. Surgical techniques require cardiopulmonary bypass which is poorly tolerated by small infants. Percutaneous techniques such as radiofrequency perforation can be challenging. The hybrid technique consists of perventricular stenting of the right ventricle outflow tract through medial sternotomy, to restore native pulmonary flow...

OBJECTIVE: Glossopharyngeal neuralgia (GPN) is a rare disorder of the ninth cranial nerve. Percutaneous radiofrequency thermocoagulation (PRT) is an established treatment for neuropathic pain. Since PRT was first applied with GPN, only a few studies have provided detailed reports on its clinical outcomes and complications, and the number of cases was small. The aim of this study was to investigate the effects, incidence rates, and severity of adverse events of computed tomography (CT)-guided PRT in 117 patients with GPN...

Multiple new options are available in the palliation of bone metastases. Most of these techniques can be used in conjunction with radiation therapy either before or after and are now giving patients who have reached dose limitations new options. These techniques can also be used with vertebroplasty (VP) to increase structural stability post tumor ablation. Localized percutaneous treatment in the bone such as thermal [radiofrequency ablation (RFA)] and light [photodynamic therapy (PDT)] have been used to destroy tumor prior to injection with cement...

Purpose: Needle track seeding in the local treatment of hepatocellular carcinoma (HCC) is not yet evaluated for catheter-based high-dose-rate brachytherapy (HDR-BT), a novel local ablative technique. Material and methods: We report a retrospective analysis of 100 patients treated on 233 HCC lesions by HDR-BT (using 588 catheters in total). No needle or catheter track irradiation was used. Minimum required follow-up with imaging was 6 months. In case of suspected needle track seeding (intra- and/or extrahepatic) in follow-up, image fusion of follow-up CT/MRI with 3D irradiation plan was used to verify the location of a new tumor deposit within the path of a brachytherapy catheter at the time of treatment...

Cryotherapy, also called Cryoablation (CA), is a technique that provides a local treatment to various pathological conditions. In Musculoskeletal tumours management, Cryoablation is well accepted and validated as a treatment in palliative cures for metastatic patients. Recently, CA has been proposed also as an alternative to radiofrequency ablation in osteoid osteoma and other benign tumour treatment with promising results. Cryotherapy with argon ice-balls as local adjuvant in open surgery is a tool that can provide enlargement of surgical margins if used properly...

There is scarce evidence for pulmonary artery denervation (PADN) as a potential treatment for chronic postcapillary pulmonary hypertension (PH). We aimed to perform a proof-of-concept of PADN in a translational model of chronic PH. Nineteen pigs with chronic postcapillary PH (secondary to pulmonary vein banding) were randomized to surgical-PADN (using bipolar radiofrequency clamps) or sham procedure. Additionally, 6 healthy animals underwent percutaneous-PADN to compare the pulmonary artery (PA) lesion generated with both approaches...
