Introduction The use of flow-diverting stents (FDS) for intracranial aneurysms has become common practice. This study aimed to evaluate ophthalmologic outcomes following carotid-ophthalmic aneurysm treatment with an FDS covering the origin of the ophthalmic artery in patients receiving aspirin and ticagrelor, through a systematic ophthalmic screening. Methods From January 2021 to October 2023, patients treated for carotid-ophthalmic aneurysms with an FDS were prospectively included in our study. All patients underwent a systematic ophthalmologic examination prior to treatment, within 15 days after embolization and 6 months post-embolization. Each patient received dual antiplatelet therapy (DAPT) with aspirin and ticagrelor for 3 months, followed by aspirin alone. Results A total of 24 patients with 25 aneurysms were included. Median age (IQR) was 55 years and 22 were females. Although all patients were asymptomatic, fundus examination revealed pathological findings on the treated side

Cognitive impairment is increasingly recognized in patients with cerebral venous congestion (CVC), yet the cognitive tools used are largely adapted from stroke and dementia research. This review examines current literature on cognitive function in CVC, including conditions such as cerebral venous sinus thrombosis (CVST), idiopathic intracranial hypertension (IIH), and dural arteriovenous fistulas (dAVFs). Special emphasis is placed on the limitations of common screening tools like the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). Cognitive dysfunction—primarily affecting executive function, processing speed, and attention—is reported in up to 86% of CVC cases, yet only about 20% of studies use validated cognitive testing tools, most of which may lack sensitivity for CVC-specific deficits. Emerging techniques such as ocular motor testing and physiological markers show promise but require further validation. There is an urgent need for standardized, CVC-s

Background Despite the expanding use of flow-diverting stents (flow diverters—FDs) for middle cerebral artery (MCA) bifurcation aneurysms, their efficacy remains contentious in this complex anatomy. Current studies report conflicting complete occlusion rates (55–92%) and significant branch stenosis/occlusion risks (8–43%), highlighting unmet needs in stent placement strategy. Methods In this retrospective cohort study combining clinical data with computational fluid dynamics (CFD), 20 MCA bifurcation aneurysms (19 patients) treated with FDs were analyzed. Patient-specific models derived from three-dimensional digital subtraction angiography underwent CFD simulations to quantify pre/post-stent hemodynamic changes. Key parameters (inflow rate, wall shear stress, residual flow volume) were compared between aneurysms with complete versus incomplete healing, and the impact of stent placement in branches of varying diameters was analyzed. Results At a median follow-up of 9 months, complete o
