The Subarachnoid Spaces in Craniosynostosis
Journal of Craniofacial Surgery, 1992A review of 85 patients with various forms of craniosynostosis showed predictable patterns of dilatation of the subarachnoid spaces in regions of compensatory skull growth. The characteristic pattern in sagittal synostosis (43 patients) included dilatation of the frontal and occipital subarachnoid spaces associated with the elongation of the ...

Capillaries in the subarachnoid space
Acta Neuropathologica, 1976The fine structure of the small vessels of the subarachnoid spaces in the rat and mouse cerebral and cerebellar cortices was examined. Small vessels with lumen under 7 mu and whose walls consisted of a single layer of endothelial cells were found. These vessels are regarded as true capillaries.

Cervicodorsal Diverticula of the Subarachnoid Space
Radiology, 1959Localized saccular dilatations of the subarachnoid space overlying the lumbar nerve roots occur with moderate frequency (4). In the authors' experience, however, similar dilatations in the cervical and dorsal areas are relatively uncommon. The purpose of this paper is to report briefly 2 cases of asymptomatic diverticular extensions of the subarachnoid

Visualization of the craniocervical subarachnoid spaces
Neuroradiology, 1977A very simple procedure is described which leads to adequate visualization of the structures in the craniocervical area that are otherwise often very insufficiently investigated during myelography routinely performed with metrizamide.

Is There a Connection Between Perivascular Space and Subarachnoid Space?
Journal of Computer Assisted Tomography, 2014Perivascular spaces (PVSs) surrounding the walls of arteries, arterioles, and venules do not directly communicate with subarachnoid spaces. There are a few reports exhibiting subarachnoid hemorrhage (SAH) and intracerebral hematomas extending to the PVSs by leakage of the leptomeninges that surround arteries.

Subarachnoid space trabeculae architecture
Clinical Anatomy, 2020AbstractIntroductionThe motion of the brain relative to the skull is influenced by the architecture of the subarachnoid space (SAS), and in particular, by the arachnoid trabeculae. In previous studies of these structures, specific shapes were identified.

The Subarachnoid Space: A Review
Pediatric Neurosurgery, 1980A historical review of our knowledge of the subarachnoid space dates from the ancients through the modern electron microscope era. Conflicting observation resulted from various methods of tissue preservation and species variability. A comparative sub-microscopic study shows striking similarities in the ultrastructure and distribution of the ...

Anatomy of the Ventricles, Subarachnoid Spaces, and Meninges
Neuroimaging Clinics of North America, 2022The ventricular system, subarachnoid spaces, and meninges are structures that lend structure, support, and protection to the brain and spinal cord. This article provides a detailed look at the anatomy of the intracranial portions of these structures with a particular focus on neuroimaging methods.

Transvascular in vivo microscopy of the subarachnoid space
Journal of NeuroInterventional Surgery, 2022BackgroundThe micro-architectonics of the subarachnoid space (SAS) remain partially understood and largely ignored, likely the result of the inability to image these structures in vivo. We explored transvascular imaging with high-frequency optical coherence tomography (HF-OCT) to interrogate the SAS.MethodsIn vivo HF-OCT was performed in 10 dogs in ...
