Vein of Galen malformation (VOGM), the result of arteriovenous shunting between choroidal and/or subependymal arteries and the embryologic prosencephalic vein, is among the most severe cerebrovascular disorders of childhood. We hypothesized that in situ analysis of the VOGM lesion using endoluminal tissue sampling (ETS) is feasible and may advance our understanding of VOGM genetics, pathogenesis, and maintenance. ⋯ ETS may supplement investigations aimed at development of a molecular-genetic taxonomic classification scheme for VOGM. Moreover, results may eventually inform the selection of personalized pharmacologic or genetic therapies for VOGM and cerebrovascular disorders more broadly.

Cerebellopontine angle (CPA) meningiomas present challenges given their proximity to neurovascular structures. Postoperative complications and persistent symptoms can debilitate patients, and our ability to predict recovery course remains variable. Here, we examine the presentation, management, and outcomes of patients with CPA meningiomas. ⋯ GTR remains critical to achieve optimal symptom control and reduce progression/recurrence rates for CPA meningiomas. Drilling the IAC is an important predictor of GTR in tumors with intracanalicular invasion.

The role of bypass surgery in intracranial atherosclerotic steno-occlusive diseases (ICADs) remains controversial. We aimed to analyze the surgical outcomes of bypass surgery in patients with the ICADs in a single tertiary institution. ⋯ Low-flow bypass surgery showed acceptable treatment outcomes in the prevention of recurrent stroke.

Communication has a well-established effect on improving outcomes. The current study evaluated the effect of multidisciplinary preoperative team communication using a digital huddle software platform on operating room costs. ⋯ The implementation of a digital huddle software platform resulted in an OR utilization and supply cost decrease among participants during a period when the overall nonparticipating control cohort experienced an increase in cost.

The optimal surgical management of thoracic schwannomas (TSs) remains contentious, with various approaches proposed. Video-assisted thoracoscopic surgery (VATS) and combined VATS with neurosurgical procedures have shown promise, particularly for Eden type IV and III lesions. However, unanimous consent on the most effective surgical intervention and understanding of prognostic factors for tumor recurrence needs to be improved. The aim of this study was to elucidate the optimal surgical approach according to the Eden type and investigate predictive factors for TS recurrence. ⋯ For Eden type III TSs, neurosurgical and VATS combined surgery achieved better outcomes than neurosurgery alone; for Eden type IV TSs, VATS achieved better results than OT. For Eden types I and II, hemilaminectomy and bilateral laminectomy and laminectomy and TPD achieved similar outcomes, respectively.
