Preoperative magnetic resonance imaging (MRI) is a standard component of the preoperative clinical workup for patients before microvascular decompression (MVD). However, its ability to accurately exclude neurovascular compression of the trigeminal nerve is not well understood. ⋯ Preoperative MRI may offer a high predictive value for neurovascular conflict and should be part of the standard preoperative care workup for patients with trigeminal neuralgia. However, lack of neurovascular conflict on preoperative imaging is not sufficient to exclude patients from undergoing MVD.

An extensive spinal epidural abscess is a devasting infection of the multiple-level epidural space. Emergent surgical decompression is required to remove the abscess and decompress the affected spinal cord. This study evaluated the efficacy of unilateral laminotomy for bilateral decompression (ULBD) in the treatment of extensive spinal epidural abscesses. ⋯ As a minimally invasive technique, ULBD is a safe and effective treatment for extensive spinal epidural abscesses in critically ill patients. Moreover, the use of an ultrasonic bone curette not only safely accelerates over-the-top decompression but also flushes the epidural abscess with copious amount of cold saline.

Early cerebral infarction (ECI) is an independent factor associated with poor outcome following aneurysmal subarachnoid hemorrhage (aSAH). We aimed to test the association between ECI and prior global impairment of cerebral perfusion. ⋯ Our study demonstrated that ECI is strongly associated with the prior occurrence of global impairment of cerebral perfusion, independent of World Federation of Neurological Surgeons grade. These patients may benefit from more intensive and systematic prevention of impaired cerebral perfusion, particularly in poor-grade patients.

Pilocytic astrocytomas account for approximately 5%-6% of all gliomas and are most commonly diagnosed between the ages of 8 and 13 years. Although they may occur throughout the neuraxis, approximately two thirds arise from the cerebellum and optic pathway. Other locations of origin include midline structures such as thalamus, hypothalamus, and periventricular regions. Surgical approaches to lateral or third ventricular tumors include anterior transcallosal, subfrontal translamina terminalis, and anterior transcortical approaches. The Aurora Surgiscope is a single-use, disposable minimally invasive neurological endoscope designed for intraparenchymal hemorrhage evacuation. We present the successful use of this system to aid resection of a large intraventricular pilocytic astrocytoma. ⋯ Extensive sulcal dissection preceding placement of the endoscope allowed access to the intraventricular space with minimal passage of parenchymal tissue. High-definition visualization was provided and allowed the operating surgeon to freely use both hands during surgery.

Given the neurotrauma that soldiers might face during wars, a byproduct of such devastating neurosurgical conditions can be novel data, which can act as a catalyst for potentially paradigm-shifting research. We aimed to identify the impact of major U.S. military campaigns on military neurosurgery literature across defined time periods. ⋯ Since World War II, the military has contributed significant historical developments to neurosurgery, the most prominent being after the Iraq and Afghanistan wars and the introduction of the Department of Defense Trauma Registry.
