To prospectively evaluate the diagnostic value of 3.0 Tesla magnetic resonance 3-dimensional sampling perfection with application-optimized contrast using different flip angle evolution (3D-SPACE) in the detection of sinus wall invasion and sinus patency in parasinus meningiomas. ⋯ With an integrative presentation of parasinus meningioma, wall invasion, lumen patency, and collateral veins, high-resolution 3D-SPACE imaging provides a reliable technique to accurately assess venous sinus invasion preoperatively.

Hospital readmission is a key surgical quality metric associated with financial penalties and greater healthcare costs. We examined the clinical risk factors and postoperative complications associated with 30-day unplanned hospital readmissions after cranial neurosurgery. ⋯ Unplanned hospital readmission after cranial neurosurgery is a common event. The identification of high-risk patients who undergo cranial procedures might allow hospitals to reduce unplanned readmissions and their associated healthcare costs.

To assess the validity of the proposed NeuroSpine Surgery Research Group Classification System through a retrospective analysis of patients treated surgically for lumbar facet joint cysts at a single institution. ⋯ The proposed NeuroSpine Surgery Research Group Classification System for lumbar facet joint cysts is effective in identifying patients most likely to endure a recurrent cyst after decompressive surgery. Patients with grades 4 and 5 cysts should be considered for decompressive surgery with concomitant stabilization of the involved segments on initial presentation.

We analyzed the applicability of the Simpson grading system to estimate the risk of tumor recurrence after microsurgery for recurrent meningiomas. ⋯ Surgery for recurrent meningiomas is not generally associated with an increased risk of postoperative complications compared with resection of primary diagnosed tumors. However, the Simpson grade and EOR in recurrent meningiomas correlated poorly with further tumor relapse. The lower prognostic value of the tumor remnants left behind during microsurgery for recurrent meningiomas should be considered when operating on lesions that can be surgically challenging.

Intraoperative aneurysm rupture (IOAR) is a common complication during intracranial aneurysm (IA) surgery. In light of the paradigm shift regarding IA selected for clipping in the post-International Subarachnoid Aneurysm Trial (ISAT) era, we aimed to evaluate the risk factors and effects of IOAR in an institutional series of clipped ruptured IA (RIA) and unruptured IA (UIA). ⋯ IOAR was independently predicted by the ruptured status, location, and size of IA and by initial severity of aneurysmal bleeding and pretreatment rebleeding. The influence of IOAR differed between RIA and UIA cases.
