Superior anastomotic vein hypoplasia as a unique predisposing factor for cerebral venous hypertension and atraumatic non-aneurysmal subarachnoid hemorrhage: A case report

open access: yesInterdisciplinary Neurosurgery, 2021
Subarachnoid hemorrhage (SAH) is a major cause of hemorrhagic stroke with substantial morbidity and mortality. Cerebral venous and/or sinus thrombosis can result in SAH in rare occasions, representing a mechanism for atraumatic, non-aneurysmal SAH that ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Quantification of the Dynamics of the Vascular Flows in the Cerebral Arterial and Venous Trees

open access: yesBiomedicines
Objective: Cerebral vascularization is made of the symmetrical arterial system, with muscular walls, and the venous system, more variable and dominated by sinuses and jugular veins.

Why should we report posterior fossa emissary veins?

open access: yesDiagnostic and Interventional Radiology, 2014
Posterior fossa emissary veins are valveless veins that pass through cranial apertures. They participate in extracranial venous drainage of the posterior fossa dural sinuses.

Intracranial Venous Alteration in Patients With Aneurysmal Subarachnoid Hemorrhage: Protocol for the Prospective and Observational SAH Multicenter Study (SMS)

open access: yesFrontiers in Surgery, 2022
BackgroundArterial vasospasm has been ascribed as the responsible etiology of delayed cerebral infarction in patients with aneurysmal subarachnoid hemorrhage (aSAH), but other neurovascular structures may be involved.

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Cerebral Arterial Inflow and Venous Outflow Assessment Using 4D Flow MRI in Adult and Pediatric Patients

open access: yesJournal of Vascular Diseases
Background and Purpose: The cerebral circulation is highly regulated to maintain brain perfusion, keeping an equilibrium between the brain tissue, cerebrospinal fluid (CSF) and blood of the arterial and venous systems.

A time-invariant visco-elastic windkessel model relating blood flow and blood volume [PDF]

open access: yes, 2009
The difference between the rate of change of cerebral blood volume (CBV) and cerebral blood flow (CBF) following stimulation is thought to be due to circumferential stress relaxation in veins (Mandeville, J.B., Marota, J.J.A., Ayata, C., Zaharchuk, G ...
