This study aimed to describe and validate a novel ultrasound-guided intercostal peripheral nerve stimulator implantation technique. ⋯ To our knowledge, this study is the first to determine the feasibility of ultrasound-guided peripheral nerve stimulator placement in close proximity to the pleura. All the stimulator leads were accurately placed using our ultrasound-guided technique and were within 0.5-3 mm from the intercostal nerve. Although this technique might prove technically challenging, the use of ultrasound for intercostal peripheral nerve stimulator implantation appears feasible and warrants further investigation to establish this as an acceptable technique for patients.

Peripheral nerve stimulation (PNS) is a form of neuromodulation that is used to treat chronic and refractory neuropathic pain. Peripheral nerve stimulation was first described in the early 1960s when Shelden implanted a PNS device for trigeminal neuralgia. Despite PNS being known since the 1960s, technology designed specifically for PNS was lacking. Within the past few years, design-specific PNS devices have become widely available, with favorable efficacy and safety profiles. Here we report a case of design-specific PNS that provided two years of pain relief in a patient with lower extremity neuropathic pain. ⋯ This report emphasizes the recent development of design-specific PNS devices and their successful use in this patient. Peripheral nerve stimulation technology and applications have diminished the role of spinal cord stimulation devices used for the periphery. Peripheral nerve stimulation should be considered for patients with isolated extremity pain, especially in those with spinal abnormalities (e.g., arachnoid cyst).

Cancer-related abdominal and pelvic pain syndromes can be debilitating and difficult to treat. The objective of this study was to evaluate the efficacy of superior hypogastric plexus blockade or neurolysis (SHPN) for the treatment of cancer-related pelvic pain. ⋯ SHPN was an effective and relatively safe procedure for pain associated with pelvic malignancies. There is a need for larger prospective trials.
