Complete Right Internal Carotid Artery Occlusion in Ischemic Stroke: DSA Case ReportComplete Right Internal Carotid Artery Occlusion in Ischemic Stroke: DSA Case Report

Abstract

Background: Digital subtraction angiography (DSA) is a vascular imaging modality that helps identify the location and characteristics of arterial occlusion in ischemic stroke. Case Presentation: A 60-year-old man with a history of uncontrolled hypertension and diabetes mellitus was referred with left-sided limb weakness and dysarthria lasting approximately two days. Neurological examination revealed left facial and hypoglossal nerve palsies, severe left-sided motor weakness, and a National Institutes of Health Stroke Scale (NIHSS) score of 23. Non-contrast computed tomography (CT) of the head demonstrated cerebral infarction, while DSA identified complete occlusion of the right internal carotid artery (ICA) at the carotid bifurcation. Conclusion: DSA provides anatomical information regarding arterial occlusion that complements the infarction findings on CT. Integrating clinical assessment and imaging findings is essential for understanding the vascular abnormalities underlying ischemic stroke and supporting appropriate treatment planning.
