| Abstract | ||
| Background: Stroke is a primary contributor to both mortality and disability, with ischemic stroke being the most frequently occurring type. Brain Edema (BE) is a severe complication that increases Intracranial Pressure (ICP) and worsens neurological outcomes. While Computed Tomography (CT) is the standard for BE detection, Optic Nerve Sheath Diameter (ONSD) estimations via Ultrasound (US) provides a non-invasive alternative.Objectives: This study assessed the role of ONSD measurement in detecting BE compared to CT in ischemic stroke cases.Methods: A comparative cross-sectional study included 174 cases at Benha University hospitals. Cases were divided into two groups: Group A (87 ischemic stroke cases) and Group B (87 healthy controls). ONSD was measured via US at admission and after 48 hours. BE was assessed using CT.Results: BE significantly increased in Group A after 48 hours (P=0.034) but was absent in Group B. ONSD increased significantly over 48 hours in the right (P=0.009) and left eye (P=0.040). Cases with BE had significantly larger ONSD than those without (P<0.001). ONSD predicted BE incidence with high specificity and sensitivity (RT: AUC=0.941, P<0.001; LT: AUC=0.805, P<0.001).Conclusion: ONSD measurement is a reliable, non-invasive tool for detecting and monitoring BE in ischemic stroke cases, demonstrating strong correlation with CT findings and potential utility in guiding timely interventions. | ||
