Peripheral Nerve Field Stimulation: Feasibility of Subcutaneous Placement under Ultrasound Guidance

Abstract Background: Although peripheral nerve field stimulation [PNFS] does not have one precise target, accurate placement within the subdermal space is critical for optimal results. Findings: In the present report, a 71-year-old female underwent a PNFS trial. Under ultrasound guidance, the physician placed two leads. Following the trial, the patient reported clinically significant improvements in pain and function. Conclusions: Ultrasound guidance provided delineation between the subcutaneous and muscular layers, which afforded visualization of lead depth. However, future prospective cohort studies and randomized controlled trials are needed to definitely evaluate the use of ultrasound guidance for lead placement.
