Sponsor's own description

Prevalence of Large Vessel Occlusion among acute ischemic stroke patients in Assiut University hospitals 1. Study Objectives Primary Objective: \- To determine the prevalence of LVO among acute ischemic stroke (AIS) patients presenting to Assiut University hospitals Secondary Objectives: * To describe clinical and radiological characteristics of LVO patients. * To assess factors associated with LVO (age, sex, stroke severity, comorbidities). 2. Study Design * Type: single center, prospective observational cross-sectional study * Duration: 12-month recruitment period * Setting: Assiut university hospitals, stroke unit. 3. Study Population Inclusion Criteria: * Adults (≥18 years) * Diagnosed with acute ischemic stroke within 24 hours of symptom onset * Underwent vascular imaging (CTA or MRA) on admission Exclusion Criteria: * Hemorrhagic stroke * Stroke mimics * Incomplete imaging data 4. Definitions Large Vessel Occlusion (LVO) defined as occlusion in: * Intracranial ICA * M1 or proximal M2 segments of MCA * Basilar artery ± Optional: A1 6. Data Collection Clinical Data: * Demographics (age, sex) * Risk factors (HTN, DM, AF, CAD, smoking) * NIHSS on admission and discharge mRS on admission and discharge * Onset-to-door time * Imaging modality used Imaging Data: * Site of occlusion * ASPECTS (optional) * Collateral status (optional if available) Hospital Data: * Facility type (public vs private) * Door-to-CT and door-to-CTA times 8. Analysis Plan * Primary: Prevalence of LVO = Number of LVO cases / Total AIS patients with vascular imaging * Subgroup analysis: By age group, sex, region, NIHSS * Secondary: Logistic regression to identify predictors of LVO
