Spinal cord stimulation is a known modality for the treatment of chronic back and neck pain. Traditionally, spine surgeons and pain physicians perform the procedures. We report our experience in performing neuromodulation procedures in an outpatient interventional neuroradiology practice. ⋯ Neuromodulation procedures can be performed safely in an outpatient interventional radiology setting. Although the infection rate was relatively higher in this study population, the other complication rates and trial-to-implant ratio are similar to published data.

Review Meta Analysis
Seizure control for intracranial arteriovenous malformations is directly related to treatment modality: a meta-analysis.
Seizures are a common presenting sign of intracranial arteriovenous malformations (AVMs). The object of this meta-analysis was to determine if the modality selected to treat AVMs affects the rate of seizure outcomes. ⋯ This is the first meta-analysis designed to study relative rates of seizure outcomes following the currently utilized AVM treatment modalities. In general, MS results in the highest proportion of seizure control. However, if SRS results in successful obliteration of the AVM, then this modality is the most effective in achieving seizure control.

In acute ischemic stroke, good outcome following successful recanalization is time dependent. In patients undergoing endovascular therapy at our institution, recanalization times with the Solitaire stent were retrospectively evaluated to assess for the presence of a learning curve in achieving rapid recanalization. ⋯ There is a learning curve involved in the efficient use of the Solitaire stent in endovascular acute stroke therapy. Along with improvements in patient transfer to angiography and improved efficiency with intracranial access, mastering this device contributed significantly towards reducing recanalization times.

Traditional balloon assisted coil embolization techniques for intracranial aneurysms require a single lumen balloon to remodel the aneurysm neck and a separate microcatheter to place coils. Here we report utilization of a single coaxial dual balloon microcatheter to achieve both coil placement and neck remodeling in a series of intracranial and cervical arterial aneurysms. ⋯ Aneurysmal neck remodeling and coil embolization can both be achieved using a single coaxial dual lumen balloon microcatheter in selected oblong intracranial and cervical arterial aneurysms.

Tentorial dural arteriovenous fistula (DAVF) as a cause of trigeminal neuralgia is extremely rare. Although less than 10 cases have been reported in the literature, all cases presented with ipsilateral trigeminal neuralgia. Here we report a unique case of tentorial DAVF manifesting as contralateral trigeminal neuralgia. ⋯ Transarterial Onyx embolization resulted in near complete obliteration of the fistula with immediate resolution of facial pain. The patient remains symptom free and without evidence of recurrence during 9 months of follow-up. Transarterial Onyx embolization may be an effective treatment modality for such an usual case.
