One of the most challenging aspects of the surgical treatment of tuberculum sellae meningioma is to control the involvement of the inferomedial side of the optic nerve, which is not directly visualized by an ipsilateral approach and thus requires optic nerve mobilization. ⋯ This approach allowed lower mobilization of the compromised optic nerve, better preservation of the vascularization of the visual pathways, and direct access to the inferomedial side of the optic nerve.

Substantial clinical benefit (SCB) represents a threshold above which patients recognize substantial improvement and represents a rational target for defining clinical success. In adult spinal deformity (ASD) surgery, previous fusions may impact outcomes after deformity correction. ⋯ Patients undergoing revision surgery have worse baseline HRQOL and deformity. Although they do not achieve the same absolute level of 2-year HRQOL outcome, they have a similar likelihood of reaching SCB threshold for improvement in 2-year HRQOL.

Preoperative embolization may facilitate skull base meningioma resection, but its safety and efficacy in the Onyx era have not been investigated. In this retrospective cohort study, we evaluated the outcomes of preoperative embolization of skull base meningiomas using Onyx as the primary embolysate. ⋯ For appropriately selected skull base meningiomas supplied by dura mater-based arterial pedicles without distal cranial nerve supply, preoperative embolization with current embolysate technology affords substantial tumor devascularization with a low complication rate.

Approximately 12% of intracerebral hemorrhages (ICHs) occur in the thalamus. Understanding the anatomic regions involved with thalamic hemorrhages is potentially useful, offering the physician a more accurate prognosis for patient outcomes. This study was performed to determine if thalamic hemorrhage location observed on a computed tomography (CT) scan was predictive of neurologic outcomes. ⋯ In thalamic hemorrhages, patient prognosis may be influenced by hemorrhage location, with posterior and lateral hemorrhages demonstrating better clinical outcome versus hemorrhages in other locations. This is potentially valuable because hemorrhage location affords the treating physician a readily available prognostic factor when assessing intracranial hemorrhages.

Comparative Cost Analysis for the Surgical and Endovascular Treatment of Ruptured Intracranial Aneurysms in Taiwan: A Nationwide Population-Based Cohort Study.
Using a database that enabled longitudinal follow-up, we assessed the cost, outcome, complications, and readmission rate of ruptured cerebral aneurysms repaired by surgical clipping and endovascular coiling. ⋯ In Taiwan, the total hospital costs for the surgical clipping of cerebral aneurysms were higher than for endovascular coiling, and the surgical results were associated with significant complications. We suggest that the indications for coiling might need to be expanded from the current standards dictated by the guidelines in Taiwan.
