Surgical Treatment of Traumatic Intracranial Aneurysms: Experiences at a Single Center over 30 Years.
Traumatic intracranial aneurysm (tIA) is rare and is associated with high rates of morbidity and mortality. We describe our experiences with tIA at our institution. ⋯ tIA is an uncommon complication of head trauma. tIA should be considered when unexpected new symptoms develop in patients with head trauma. Early diagnosis and prompt treatment could help to improve final clinical outcomes.

Cerebellar arteriovenous malformation (C-AVM) is poorly tolerated because of its aggressive natural history. The aim of this study was to delineate long-term outcomes of Gamma Knife stereotactic radiosurgery (GKRS) for C-AVM. ⋯ GKRS is a reasonable intervention for C-AVMs. Symptomatic complications are rare, and the long-term outcomes are favorable.

Randomized Controlled Trial
Evaluation of Meropenem Penetration into Cerebrospinal Fluid in Patients with Meningitis after Neurosurgery.
Meropenem is important for management of postneurosurgical meningitis, but the data about its penetration into cerebrospinal fluid (CSF) are inadequate. This prospective, open-label study investigated the pharmacokinetic profile of meropenem in patients with postneurosurgical meningitis, especially its CSF penetration. ⋯ Dosing regimens of meropenem 1 g every 6 hours and 2 g every 8 hours provided higher CSF penetration than 1 g every 8 hours. A higher dose and shorter dosing interval of meropenem may be more useful for clearance of pathogens.

Multicenter Study
Transforaminal resection of cervical dumbbell schwannomas in patients with additional tumors.
It is rare for 2 primary tumors to occur simultaneously in a patient. Management of cervical dumbbell schwannomas (CDSs) with concurrent tumors (CTs) requires a specific neurosurgical strategy. The primary objective of this study is to investigate surgical strategies for CDSs with CTs while preserving as much of the mechanically relevant bone structures as possible. ⋯ In most patients, the stability of the cervical spine can be preserved with low invasive microsurgical or endoscopic transforaminal resection. CTs could be surgically treated sequentially after microscopic- and endoscopic-assisted resection of CDSs.

We sought to compare the prognosis of clival chordomas with different dural penetration and establish the relationship between dural penetration and platelet-derived growth factor receptor (PDGFR)-β signaling pathway. ⋯ Clival chordomas have different degrees of dural penetration. Patients with chordomas with serious dural penetration have poorer prognosis. Higher expression of PDGFR-β is related to more serious dural penetration of clival chordomas.
