In this study, we aimed to identify prognostic factors in anaplastic hemangiopericytoma (AHPC) and clinical behaviors that differentiate primary and secondary AHPC. ⋯ Gross total resection and PRT following surgery are recommended in AHPC. Identifying clinical behaviors that differentiate primary and secondary AHPC improved our understanding of this type of tumor and guided treatment strategies.

The aim of the study was to examine the clinical effect of postoperative hyperbaric oxygen (HBO) therapy on symptoms and signs in the ventriculoperitoneal (VP) shunt insertion treatment of idiopathic normal pressure hydrocephalus (iNPH). ⋯ HBO therapy combined with VP shunt is expected to improve the effect of iNPH treatment, especially for cognitive performance.

Complementary relation between direct and indirect bypass in progress of collateral circulation in moyamoya disease.
One of the important aims of surgery for moyamoya disease is to establish indirect revascularization. The purpose of this study was to assess the progress of the middle meningeal artery (MMA) after our novel preservation method and to evaluate the relation between direct and indirect bypass in the chronic stage. ⋯ In moyamoya disease, the MMA could be developed as a pathway for indirect revascularization even after simple preservation, especially in pediatric patients. The progress of the MMA and the STA occurs through their synergistic interaction, and the balance might be decided based on their complementary relations in the chronic stage.

Fluorescein sodium salt is widely used in medicine as fluorescein isothiocyanate and commonly named fluorescein (FL). This fluorophore has been used as a fluorescent tracer for many applications, especially in ophthalmic surgery. It was initially used in neuro-oncology in 1948 to control tumor resection margins. After a transient disuse, it has recently had a second spring with the development of dedicated filters for operating microscopes, although it is still under evaluation in clinical use. The aim of this study is to contribute to the investigation according to which FL-guided surgery for high-grade glioma (HGG) is related to better rates of gross total resection (GTR) and so to a better outcome. ⋯ Intraoperative fluorescein-guided surgery showed safety and feasibility. Our and other studies suggest an improvement of GTR rate in HGG than nonuse.

Surgical treatment of meningiomas next to venous sinuses is difficult because of their irregular growth patterns and infiltration into the venous sinuses, making gross total resection impossible in some patients. We evaluated the postoperative clinical and neurologic course of this tumor subgroup. ⋯ Surgical removal of meningiomas adjacent to venous sinuses reduces neurologic impairment and enables local tumor control in most patients. Tumor size, bone infiltration, and higher World Health Organization grade are important predictors of tumor recurrence.
