Journal of Neurosurgery: Pediatrics, Ahead of Print. OBJECTIVEEndoscope-assisted repair of sagittal craniosynostosis was adopted at St. Louis Children’s Hospital in 2006. This study examines the first 100 cases and reviews the outcomes and evolution of patient care protocols at our institution.METHODSThe authors performed a retrospective chart review of the first 100 consecutive endoscopic repairs of sagittal craniosynostosis between 2006 and 2014.… Read More...

Journal of Neurosurgery, Ahead of Print. Stenosis of the transverse sinus (TS) and sigmoid sinus (SS), with a trans-stenosis pressure gradient, has been implicated in the pathophysiology of idiopathic intracranial hypertension (IIH). MRI has shown improvement in TS and SS stenosis after high-volume lumbar puncture (HVLP) in a subset of patients with IIH.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVESurgical approaches to the ventrolateral pons pose a significant challenge. In this report, the authors describe a safe entry zone to the brainstem located just above the trigeminal entry zone which they refer to as the “epitrigeminal entry zone.”METHODSThe approach is presented in the context of an illustrative case of a cavernous malformation and is compared with the other commonly described approaches to the ventrolateral pons.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEMoyamoya disease (MMD) is occasionally accompanied by intracranial aneurysms. The purpose of this study was to delineate the efficacy of the authors’ current surgical strategy in the management of MMD-associated aneurysms of different types.METHODSBetween January 2007 and March 2016, a consecutive cohort of 34 patients with 36 MMD-associated aneurysms was enrolled in this prospective single-center cohort study.… Read More...

Journal of Neurosurgery, Ahead of Print. The authors’ initial experience with the endoscopic extradural supraorbital approach to the temporal pole and adjacent area is reported. Fully endoscopic surgery using the extradural space via a supraorbital keyhole was performed for tumors in or around the temporal pole, including temporal pole cavernous angioma, sphenoid ridge meningioma, and cavernous sinus pituitary adenoma, mainly using 4-mm, 0° and 30° endoscopes and single-shaft instruments.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe aim of this study was to analyze the early radiological response of melanoma brain metastases to single high-dose irradiation and to reveal possible correlations between tumor radioresponsiveness and patient clinical outcomes.METHODSThe authors performed a retrospective analysis of the medical data for all patients with melanoma brain metastases who had undergone Gamma Knife radiosurgery (GKRS) and follow-up MRI examinations with standard protocols at regular 2- to 3-month intervals.… Read More...

Journal of Neurosurgery, Ahead of Print. Brain shifts following microsurgical clip ligation of anterior communicating artery (ACoA) aneurysms can lead to mechanical compression of the optic nerve by the clip. Recognition of this condition and early repositioning of clips can lead to reversal of vision loss.The authors identified 3 patients with an afferent pupillary defect following microsurgical clipping of ACoA aneurysms.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe aim of this study was to define predictive factors for rupture of middle cerebral artery (MCA) mirror bifurcation aneurysms.METHODSThe authors retrospectively analyzed the data in patients with ruptured MCA bifurcation aneurysms with simultaneous presence of an unruptured MCA bifurcation mirror aneurysm treated in two neurosurgical centers.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEThe price of coils used for intracranial aneurysm embolization has continued to rise despite an increase in competition in the marketplace. Coils on the US market range in list price from $500 to $3000. The purpose of this study was to investigate potential cost savings with the use of a price capitation model.METHODSThe authors built a clinical decision analytical tree and compared their institution’s current expenditure on endovascular coils to the costs if a capped-price model were implemented.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEResection of intraaxial tumors adjacent to the optic radiation (OR) may be associated with postoperative visual field (VF) deficits. Intraoperative navigation using MRI-based tractography and electrophysiological monitoring of the visual pathways may allow maximal resection while preserving visual function.… Read More...
