Mathematical modelling of the CSF system: effects of microstructures and posture on optic nerve subarachnoid space dynamics
Holmlund, Petter; Støverud, Karen-Helene; Eklund, Anders (Peer reviewed; Journal article, 2022)Background: The pressure difference between the eye and brain in upright postures may be affected by compartmentalization of the optic nerve subarachnoid space (ONSAS). Both pressure and deformation will depend on the ... -
Prediction of cerebral perfusion pressure during carotid surgery – A computational fluid dynamics approach
Holmgren, Madelene; Holmlund, Petter; Støverud, Karen-Helene; Zarrinkoob, Laleh; Wåhlin, Anders; Malm, Jan; Eklund, Anders (Peer reviewed; Journal article, 2022)Background: Maintaining cerebral perfusion pressure in the brain when a carotid artery is closed during vascular surgery is critical for avoiding intraoperative hypoperfusion and risk of ischemic stroke. Here we propose ... -
Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study
Emendi, Monica; Støverud, Karen-Helene; Tangen, Geir Arne; Ulsaker, Håvard; Manstad-Hulaas, Frode; Di Giovanni, Pierluigi; Dahl, Sigrid Kaarstad; Langø, Thomas; Prot, Victorien Emile (Peer reviewed; Journal article, 2023)Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative ...
