Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe optimal surgical modality for moyamoya disease (MMD) remains unclear. The aim of this study was to compare the surgical effects of direct bypass (DB) and indirect bypass (IB) in the treatment of adult ischemic-type MMD.METHODSAdult patients with ischemic-type MMD who underwent either DB or IB from 2009 to 2015 were identified retrospectively from a prospective database.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEDespite their technical simplicity, cranioplasty procedures carry high reported morbidity rates. The authors here present the largest study to date on complications after cranioplasty, focusing specifically on the relationship between complications and timing of the operation.METHODSThe authors retrospectively reviewed all cranioplasty cases performed at Harborview Medical Center over the past 10.75 years.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe goal of this study was to investigate the impact of stereotactic radiosurgery (SRS), BRAF status, and targeted and immune-based therapies on the recurrence patterns and factors associated with overall survival (OS) among patients with melanoma brain metastasis (MBM).METHODSA total of 366 patients were treated for 1336 MBMs; a lesion-based analysis was performed on 793 SRS lesions.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe pathophysiology of chronic noncommunicating hydrocephalus (ncHC) is poorly understood. This present study explored whether lessons about the pathophysiology of this clinical entity might be retrieved from results of overnight monitoring of pulsatile and static intracranial pressure (ICP) and ventricular infusion testing.METHODSThe study cohort included adult patients (20 years of age) with chronic ncHC due to aqueductal stenosis in whom symptoms had lasted a minimum of 6 months.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEBlunt cerebrovascular injuries (BCVIs) following trauma carry risk for morbidity and mortality. Since patients with BCVI are often asymptomatic at presentation and neurological sequelae often occur within 72 hours, timely diagnosis is essential. Multidetector CT angiography (CTA) has been shown to be a noninvasive, cost-effective, reliable means of screening; however, the false-positive rate of CTA in diagnosing patients with BCVI represents a key drawback.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEInitiation of external CSF drainage has been associated with a significant increase in rebleeding probability after aneurysmal subarachnoid hemorrhage (aSAH). However, the implications for acute management are uncertain. The purpose of this study was to evaluate the role of the amount of drained CSF on aneurysmal rebleeding.METHODSConsecutive patients with aSAH were analyzed retrospectively.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe first choice of treatment in cases of vertebral artery dissecting aneurysms (VADAs) is endovascular internal trapping (EIT) of the dissecting segment using coils. However, this procedure carries the risk of medullary infarction, and the risk factors for this complication are not well understood.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEVitamin D deficiency has been associated with a variety of negative outcomes in critically ill patients, but little focused study on the effects of hypovitaminosis D has been performed in the neurocritical care population. In this study, the authors examined the effect of vitamin D deficiency on 3-month outcomes after discharge from a neurocritical care unit (NCCU).METHODSThe authors prospectively analyzed 25-hydroxy vitamin D levels in patients admitted to the NCCU of a quaternary care center over a 6-month period.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe middle clinoid process (MCP) is a bony projection that extends from the sphenoid bone near the lateral margin of the sella turcica. The varied prevalence and morphological features of the MCP in populations stratified by age, race, and sex are unknown; however, the knowledge of its anatomy and preoperative recognition on CT scans can aid greatly in complication avoidance and management.… Read More...
