Aneurysms of the intracranial segment of the ophthalmic artery trunk. case report and systematic literature review [PDF]

open access: yes, 2017
Aneurysms arising from the ophthalmic artery trunk (OAT) are very rare, particularly in the artery's intracranial course. The onset of a subarachnoid hemorrhage (SAH) from a ruptured OAT aneurysm in this segment is extremely rare.

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 ...

Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter [PDF]

open access: yes, 2016
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac.

Effects of upstream bifurcation and bend on the blood flow in a cerebral aneurysm

open access: yesJournal of Biomechanical Science and Engineering, 2017
Mechanisms of development, growth, and rupture of a cerebral aneurysm have been studied by computational fluid dynamics (CFD), calculating hemodynamic parameters, such as wall shear stress, oscillatory shear index (OSI), and relative residence time (RRT).

Computational modelling of clot development in patient‐specific cerebral aneurysm cases

open access: yesJournal of Thrombosis and Haemostasis, 2016
Essentials Clotting in cerebral aneurysms is a process that can either stabilize the aneurysm or lead to rupture. A patient‐specific computational model capable of predicting cerebral aneurysm thrombosis is presented.

Cerebral hyperperfusion syndrome following combined aneurysm trapping and low-flow bypass for fusiform aneurysm of the middle cerebral artery

open access: yesInterdisciplinary Neurosurgery
The mechanism of cerebral hyperperfusion syndrome (CHS) following aneurysm surgery remains unclear. We report the case of a 66-year-old woman with an unruptured large fusiform-shaped aneurysm of the left middle cerebral artery.
