Novel Use of Noninvasive High-Intensity Focused Ultrasonography for Intercostal Nerve Neurolysis in a Swine Model.
High-intensity focused ultrasound (HIFU) is a noninvasive thermal ablation technique. High-intensity focused ultrasound has been used in small-animal models to lesion neural tissue selectively. This study aimed to evaluate the efficacy of HIFU in a large-animal model for ablation of nerves similar in size to human nerves. ⋯ High-intensity focused ultrasound may be used as a noninvasive neurolytic technique in swine. High-intensity focused ultrasound may have potential as a neuroablation technique for patients with chronic and cancer pain.

Case ReportsSpinal Epidural Hematoma After Spinal Cord Stimulator Trial Lead Placement in a Patient Taking Aspirin.
Spinal epidural hematoma is a rare, but potentially devastating, consequence of accessing the epidural space for anesthesia or interventional pain procedures. There is no consensus to stop aspirin therapy before interventional chronic pain procedures. ⋯ The only variable that could have led to our patient's epidural hematoma is aspirin. This is the first reported case of aspirin leading to an epidural hematoma following an interventional chronic pain procedure. Prior to interventional pain procedures, one should contemplate cessation of aspirin therapy because there are, at present, no consensus guidelines to direct such a decision.
