A 74-year-old man presented to the ED with acute chronic exertional dyspnea of 5-day duration. As part of his previous evaluation, 5 months earlier, he had undergone cardiopulmonary stress testing, routine laboratory evaluation, and chest radiography that were unremarkable. Over the subsequent months, he had waxing and waning exercise capacity until his incident hospitalization; the exercise was limited to < 40 meters. ⋯ On physical examination, he was afebrile and normotensive with a sinus tachycardia of 125 beats per minute. He was noted to be tachypneic with a respiratory rate of 24 breaths per minute and saturation of 95% on room air. Examination of the chest showed diminished breath sounds over left lower lung fields with scattered end expiratory wheezing.

High-frequency (10-kHz) spinal cord stimulation (SCS) continues to be an emerging therapy in chronic pain management. The same complications that plagued earlier SCS systems may affect newer stimulation technologies, although there is limited data on the type of complications and surgical management of these complications. ⋯ This retrospective 5-year analysis of complications from10-kHz SCS provides a real-world assessment of safety data unique for this stimulation modality. This analysis may help inform future clinical decisions, lead to device enhancement and optimization, and improve mitigation of risks to provide safe and efficacious use of 10-kHz SCS.
