Newer systems now incorporate technology that transmits electrical stimulation through wearable, wireless, external generators. 1 These generators can be relatively bulky and require intermittent revision to replace batteries. Historically, these devices have relied on insertion of an implantable pulse generator as well as the peripheral nerve stimulation lead. The demand for innovative technologies to treat chronic pain effectively and safely has fostered a new generation of peripheral nerve stimulation devices. If migration does occur, the potential impact of scar tissue on removal should be considered. Thorough patient education, early postimplantation assessment, and extended routine follow-up are necessary to decrease lead-associated complications. Neurologic complications of peripheral nerve stimulator implantation are rare, but device-associated complications, specifically lead migration, remain a source of long-term problems that can result in decreased coverage of the intended neural target. Initial unsuccessful removal by traction resulted in retained fragments and need for open surgical removal. Results:īoth patients experienced lead migration to the skin resulting in erythema and need for lead removal. Both peripheral nerve stimulators were confirmed with fluoroscopy, and each patient was followed up every 2 months for the following 2 years. Case 2 describes a 54-year-old woman with left shoulder pain who underwent an uncomplicated ultrasound-guided percutaneous lead placement near the axillary nerve through a deltoid approach. Methods:Ĭase 1 describes a 61-year-old man with chronic groin pain who underwent an uncomplicated ultrasound-guided ilioinguinal peripheral nerve lead implantation. This article describes 2 cases of complications from lead migration. Common complications include infection, nerve damage, and migration of stimulating leads. They transmit electrical stimulation through implanted leads and wireless, wearable, external generators. Peripheral nerve stimulators have emerged as a new generation of advanced modalities to treat chronic pain and avoid opioids.
