To investigate the clinical efficacy of navigation-guided minimally invasive surgery in patients with hypertensive basal ganglia hemorrhage. ⋯ Under certain conditions, compared with standard craniotomy and hematoma evacuation, navigation-guided hematoma puncture aspiration and catheter drainage is simple, effective, and safe as a treatment for hypertensive basal ganglia hemorrhage.

Dural arteriovenous fistula (DAVF) at the petrous apex with pial arterial supplies possesses complicated angioarchitecture, associates with aggressive neurologic behaviors, and associates with high risk of complications. This study aimed to summarize our experience with this type of DAVF in the last 15 years. ⋯ Supratentorial draining direction may be a risk factor for venous ectasia and SAH in petrous apex DAVFs with pial arterial supplies. The feeding pial arteries appeared to be at risk of embolization-related hemorrhagic complication and are therefore suggested to be embolized first.

Autonomic nervous system dysfunction is a known entity in strokes involving insula. It causes significant morbidity and mortality. No study to date has demonstrated autonomic nervous system dysfunction in patients with insular glioma. This is an exploratory study to identify the subclinical autonomic dysfunctions in insular glioma. ⋯ Patients with insular gliomas have significant impairment of autonomic functions, with left insular glioma showing sympathetic dominance. Suppression of autonomic function is greater in those presenting with seizures.

Intracranial aneurysm rupture is associated with a high mortality and disability despite modern medical care. Multiple aneurysms occur in nearly 16% of patients, and imaging studies of naturally occurring multiple aneurysms are valuable for computational fluid dynamics studies. In this study, we describe and analyze the hemodynamic changes produced in a distal aneurysm after the treatment of a proximal aneurysm. ⋯ The hemodynamic changes in a distal aneurysm after treatment of a proximal aneurysm showed an unfavorable profile associated with an increased theoretical risk of bleeding.

There is a need to further anatomically describe the nucleus accumbens (NA), as there is a growing neurosurgical interest in this locus but a limited understanding of its structure. In this study, we evaluated quantitative NA parameters and spatial relationships with adjacent structures found in the telencephalon. ⋯ We obtained the stereotactic coordinates of (x, y, z) = (8, 17, -8) for the NA. From this and other delineations of the described position of the NA, it is possible to contribute to stereotactic surgical atlases, improving neurosurgical interventions in this structure.
