Multicenter StudyStent-assisted Woven EndoBridge device for the treatment of intracranial aneurysms: an international multicenter study.
The Woven EndoBridge (WEB) device is an intrasaccular flow disruptor designed for wide-necked bifurcation aneurysms. These aneurysms may require the use of a concomitant stent. The objective of this study was to determine the clinical and radiological outcomes of patients undergoing stent-assisted WEB treatment. In addition, the authors also sought to determine the predictors of a concomitant stent in aneurysms treated with the WEB device. ⋯ This study demonstrates that there is no difference in the degree of aneurysm occlusion between the two groups; however, complications were more frequent in the stent group. In addition, a wider aneurysm neck predisposes to stent assistance in WEB-treated aneurysms.

Randomized Controlled Trial Multicenter StudyUse of 5-ALA fluorescence-guided surgery versus white-light conventional microsurgery for the resection of newly diagnosed glioblastomas (RESECT study): a French multicenter randomized phase III study.
Only one phase III prospective randomized study, published in 2006, has assessed the performance of 5-aminolevulinic acid (5-ALA) fluorescence-guided surgery (FGS) for glioblastoma resection. The aim of the RESECT study was to compare the onco-functional results associated with 5-ALA fluorescence and with white-light conventional microsurgery in patients with glioblastoma managed according to the current standards of care. ⋯ The authors found that 5-ALA FGS is an easy-to-use, cost-effective, and minimally time-consuming technique that safely optimizes the extent of resection in patients harboring glioblastoma amenable to a large resection.

Multicenter StudyFirst United States multicenter experience with the new-generation FRED X surface-modified flow diversion stent: feasibility, safety, and short-term efficacy.
Flow diversion created a paradigm shift in the treatment of intracranial aneurysms. The new flow redirection endoluminal device with X technology (FRED X) is the latest update of the recent Food and Drug Administration-approved FRED. The FRED X is engineered to reduce material thrombogenicity and enhance vessel healing. In this study, the authors aimed to evaluate the feasibility and early safety and efficacy of the new FRED X. ⋯ FRED X for the treatment of an intracranial aneurysm is technically feasible alone or in conjunction with intrasaccular embolization. In addition, the study results showed very promising early safety and efficacy. Follow-up studies should establish the long-term safety and efficacy profiles of this new stent.

Multicenter StudyEndoscopic endonasal repair of encephaloceles of the lateral sphenoid sinus: multiinstitution confirmation of a new classification.
Encephaloceles of the lateral sphenoid sinus are rare. Originally believed to be due to defects in a patent lateral craniopharyngeal canal (Sternberg canal), they are now thought to originate more commonly from idiopathic intracranial hypertension, not unlike encephaloceles elsewhere in the skull base. A new classification of these encephaloceles was recently introduced, which divided them in relation to the foramen rotundum. Whether this classification can be applied to a larger cohort from multiple institutions and whether it might be useful in predicting outcome is unknown. Thus, the authors' goal was to divide a multiinstitutional cohort of patients with lateral sphenoid encephaloceles into four subtypes to determine their incidence and any correlation with surgical outcome. ⋯ Endoscopic endonasal repair of lateral sphenoid wing encephaloceles is highly successful, but repair may lead to dry eye or facial numbness. True Sternberg (type I) leaks were uncommon. Failures and facial numbness occurred only in patients with type III and type IV leaks.

Multicenter StudyGrade 3 meningioma survival and recurrence outcomes in an international multicenter cohort.
Grade 3 meningioma represents a rare meningioma subtype, for which limited natural history data are available. The objective of this study was to identify demographics and pathologic characteristics, clinical and functional status outcomes, and prognostic factors in an international cohort of grade 3 meningioma patients. ⋯ This large multicenter study provides insight into the longitudinal outcomes of grade 3 meningioma, with respect to recurrence, survival, and functional status. This study affirms the survival benefit conferred by radiotherapy in this population and suggests good functional status outcomes for patients surviving to 5 years postoperatively.
