Abstract
Objective: Evaluation of risk factors and treatment outcomes of extracranial internal carotid artery stenosis using stent placement in patients with acute ischemic stroke. Subjects and Methods: A prospective descriptive study was conducted on 45 patients with acute ischemic stroke who underwent extracranial carotid artery stenting from July 15, 2024, to August 31, 2025. Results: The majority of patients were male (77.8%), with a mean age of 72.2 ± 10.94 years. Common risk factors included hypertension (46.7%), diabetes mellitus (33.3%), and smoking (24.4%). Most carotid artery stenosis lesions were diagnosed by CTA (82.2%). The mean degree of internal carotid artery stenosis was 83.53 ± 10.19%. The success rate of stent placement was 100%, with 6.7% of patients experiencing hypotension, 8.9% bradycardia, and 2.2% stroke immediately after the procedure. The proportion of patients achieving a favorable clinical outcome (mRS 0–2) at discharge and at 90 days was 90% and 92%, respectively. Conclusion: Advanced age and underlying conditions such as hypertension, diabetes mellitus, and smoking increase the risk of extracranial carotid artery stenosis and subsequent ischemic stroke. Patients who underwent extracranial carotid artery stenting achieved favorable clinical outcomes, with no mortality reported during treatment. A low NIHSS score and early intervention within the first 14 days after ischemic stroke were favorable prognostic factors for clinical outcomes at discharge and at 90 days.
