Journal of Neurosurgery, Ahead of Print. OBJECTIVE Patient-reported outcomes are increasingly used in studies of vestibular schwannoma (VS); however, few studies have examined self-evaluated facial nerve function and its relation to physician-reported outcomes. The primary objective of this study was to compare patient self-evaluations of facial disability with physician-evaluated facial nerve status and with self-evaluations of a healthy control group.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Various international and national gastrointestinal guidelines take different positions on whether ventriculoperitoneal shunt (VPS) insertion is a contraindication to percutaneous endoscopic gastrostomy (PEG). The objective of this meta-analysis was to try to answer the question of whether VPS insertion is a contraindication to PEG.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Large consecutive series on the size and location of ruptured intracranial aneurysms (RIAs) are limited, and therefore it has been difficult to estimate population-wide effects of size-based treatment strategies of unruptured intracranial aneurysms. The authors’ aim was to define the size and location of RIAs in patients diagnosed with subarachnoid hemorrhage due to aneurysm rupture in a high-volume academic center.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Glioblastoma is a primary glial neoplasm with a median survival of approximately 1 year. There are anecdotal reports that postoperative infection may confer a survival advantage in patients with glioblastoma. However, only a few case reports in the literature, along with 2 retrospective cohort studies, show some potential link between infection and prolonged survival in patients with glioblastoma.… Read More...

Journal of Neurosurgery, Ahead of Print. Sunitinib is a multiple tyrosine kinase inhibitor with antiangiogenic, cytostatic, and antimigratory activity for meningiomas. A recent clinical trial of sunitinib for treatment of recurrent Grade II and III meningiomas suggested potential efficacy in this population, but only 2 patients exhibited significant radiographic response with tumor volume reduction.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Delayed cerebral ischemia (DCI) causing cerebral infarction remains a significant cause of morbidity and mortality following aneurysmal subarachnoid hemorrhage (aSAH). Early brain injury in the first 72 hours following rupture is likely to play a key role in the pathophysiology underlying DCI but remains difficult to quantify objectively.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The aim of this study was to examine the impact of deliberate employment of postoperative hypotension on delayed postoperative hemorrhage (DPH) for all Spetzler-Ponce Class (SPC) C brain arteriovenous malformations (bAVMs) and SPC B bAVMs ≥ 3.5 cm in diameter (SPC B 3.5+).… Read More...
