Randomized Controlled Trial
Application of the Ommaya reservoir in managing ventricular hemorrhage.
Intraventricular hemorrhage (IVH) is associated with high morbidity and mortality. This study evaluated the safety and efficacy of the combined treatment of an Ommaya reservoir and conventional external ventricular drainage (EVD) using urokinase in the management of IVH. ⋯ The combined treatment approach of an Ommaya reservoir and EVD with intraventricular urokinase is safe and effective in patients with IVH. It increased clot clearance, shortened conventional catheter-based EVD duration, prolonged total drainage time, reduced the hydrocephalus incidence and mortality, and contributed to good clinical outcomes. The Ommaya reservoir provides a safe way to increase the injection times of urokinase, which accelerated clot resolution and did not increase the risk for ventriculitis infection.

Glioblastoma multiforme (GBM) is the most common malignant central nervous system tumor; however, extraneural metastasis is uncommon. Of those that metastasize extraneurally, metastases to the vertebral bodies represent a significant proportion. We present a review of 28 cases from the published literature of GBM metastasis to the vertebra. ⋯ A significant number of patients had no treatments for their spinal metastasis, although the intracranial lesions were treated extensively with surgery and/or adjuvant therapy. With increasing incremental gains in the survival of patients with GBM, clinicians will encounter patients with extracranial metastasis. As such, this review presents timely information concerning the presentation and outcomes of patients with vertebral metastasis.

Telemedicine has seen substantial growth in the past 20 years, related to technologic advancements and evolving reimbursement policies. The risks and opportunities of neurosurgical telemedicine are nuanced. ⋯ Telemedicine is effective in many health care scenarios and will become more relevant to neurosurgical patient care. We favor proceeding with legislation to reduce barriers to telemedicine's growth.

Minimally invasive spinal decompression for the treatment of spinal stenosis or disk herniation is often indicated if conservative management fails. However, the influence of old age on the risk of postoperative complications and clinical outcome is not well understood. We therefore sought to compare complication rates and outcomes after minimally invasive surgery decompression and discectomy in elderly patients with a cohort of younger patients undergoing similar procedures. ⋯ Our results indicate that minimally invasive decompressive surgery is a safe and effective treatment for elderly patients and does not pose an increased risk of complications. Future prospective studies are necessary to validate the specific advantages of the minimally invasive techniques in the elderly population.

Clinical Trial
A Blinded, Case-Control Trial Assessing the Value of SSFP MRI in the Diagnosis of Trigeminal Neuralgia.
High-resolution magnetic resonance imaging (MRI) may be a useful and readily available adjunct in identifying trigeminal neuralgia secondary to vascular contact (TNVC). This study evaluated the reliability and predictive ability of 1.5-tesla steady state free precession (SSFP) MRI sequences for the diagnosis of symptomatic vascular contact and response to operative intervention in patients with TNVC. ⋯ These results suggest the utility of SSFP MRI lies not in the diagnosis of TNVC, but rather in stratifying the likelihood of response to microvascular decompression in patients with characteristic symptoms.
