introduction: nasal inferior turbinate hypertrophy is one of the most common causes of nasal obstruction. many different surgical methods are currently available. the aim of this study was to review the efficacy and results of radiofrequency turbinatoplasty as a new method in the treatment of the large inferior nasal turbinate. materials and methods: this prospective study was conducted on 50 p...
BACKGROUND Catheter radiofrequency ablation of ventricular arrhythmias (VAs) arising from the left ventricle's papillary muscles has been associated with inconsistent results. The use of cryoenergy versus radiofrequency has not been compared yet. This study compares outcomes and complications of catheter ablation of VA from the papillary muscles of the left ventricle with either cryoenergy or r...
BACKGROUND One of the potential side effects with radiofrequency ablation (RFA) includes painful cutaneous dysesthesias and increased pain due to neuritis or neurogenic inflammation. This pain may require the prescription of opioids or non-opioid analgesics to control post-procedural pain and discomfort. OBJECTIVES The goal of this study is to compare post-procedural pain scores and post-proc...
BACKGROUND The long-term efficacy of radiofrequency ablation of renal autonomic nerves has been proven in nonrandomized studies. However, long-term safety of the renal artery (RA) is of concern. The aim of our study was to determine if cooling during radiofrequency ablation preserved the RA while allowing equivalent nerve damage. METHODS AND RESULTS A total of 9 swine (18 RAs) were included, ...
Inductive coupling is widely used for powering biomedical implants, but is inadequate when transmitting low-frequency waveforms. We demonstrate that with amplitude modulation, specific waveforms can be transmitted via integrated receiving coils and passive demodulators. An ‘inlaid electroplating’ process with through-wafer plating is used to reduce internal resistance of microcoils and provide ...
High flow arteriogenic priapism is uncommon and usually occurs after trauma to the genitoperineal area. The onset of prolonged erection can be delayed and is often relatively pain free. Arteriography in this case illustrated the causative bilateral arteriocavernosal fistulae and pseudoaneurysms. Treatment consisted of staged bilateral superselective metallic microcoil embolisations, resulting i...
STUDY DESIGN Retrospective chart review. OBJECTIVES To determine the success rate and duration of relief of repeat radiofrequency neurotomy for lumbar facet joint pain. SUMMARY OF BACKGROUND DATA Radiofrequency neurotomy is an effective but temporary management of lumbar facet pain. When pain recurs, radiofrequency neurotomy is usually repeated, but the outcome and duration of relief for re...
