Spontaneous intracranial hemorrhage (ICH) of the cerebellum can be life threatening because of mass effect on the brainstem and fourth ventricle. Suboccipital craniectomy is currently the treatment of choice for cerebellar ICH evacuation. Minimally invasive surgery (MIS) is currently being investigated for the treatment of supratentorial ICH. However, its utility for cerebellar ICH is unknown. The aim of this multicenter, retrospective cohort study is to evaluate the outcomes of MIS for cerebellar ICH. ⋯ MIS could represent a reasonable alternative to conventional surgery for the treatment of appropriately selected patients with cerebellar ICH. However, further studies are needed to clarify the perioperative and long-term risk to benefit profiles of this technique.

In thoracolumbar (TL) burst fractures, vertebral body height loss (VBHL) indicates the degree of instability and constitutes one of the decision criteria for surgical treatment. However, the relative reliability and variability of different measurement techniques for VBHL are unknown. We compared the reliability of different methods used to assess VBHL. ⋯ Based on comparative reliability analyses, we recommend the APCR method as the first-line technique and the AHCP as an alternative technique for measuring VBHL in TL burst fractures.

We analyzed the effect of specific optimization steps to reduce treatment delays in a nonacademic stroke hospital setting. ⋯ For acute reperfusion therapies, significant reductions in workflow intervals can be achieved after simple optimization methods in a nonacademic community-based hospital.

In open brain surgery, fixation of the bone flap is the final procedure. The bone flaps then fuse naturally. The objective of this study was to investigate the chronological process of bone fusion after craniotomy and autologous cranioplasty. ⋯ Bone flap fusion rates after craniotomy and cranioplasty were significantly different before 12 months, but not significantly different thereafter. Bone resorption occurred more frequently in the cranioplasty group over time.

The aim of this study is to share our experiences on a series of 21 patients with intraventricular meningiomas (IVMs). Histopathologic examinations are reviewed in detail and the cell of origin of IVMs is discussed. ⋯ Transcortical approaches using intraoperative ultrasonography and intraoperative monitoring with avoidance of eloquent cortical areas can achieve good outcomes. Resection of the choroidal attachments should be attempted. Our results indicate that IVMs do not show arachnoid cap cell phenotype and the findings support that IVMs originate from the choroid plexus epithelium or the progenitors of the choroid plexus epithelium.
