Abstract

Objective: To evaluate the treatment outcomes of extracranial internal carotid artery stenosis using stent placement in patients with acute ischemic stroke, and to analyze factors associated with treatment outcomes in the study population. 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 July 31, 2025. Results: The majority of patients were male (male-to-female ratio 4:1), with a mean age of 71,32 ± 6,31 years. Common risk factors included hypertension (51.1%), dyslipidemia (62.2%), diabetes mellitus (26.7%), and smoking (26.7%). Eccentric internal carotid artery stenosis was predominant (80%), with 8% having dissection. Severe stenosis (>70%) accounted for 86.7% of cases. The stenting success rate was 100%. Complications included hypotension (6.7%), bradycardia (8.9%), and post-procedural stroke (2.2%). The proportion of patients with favorable clinical outcomes (mRS 0–2) at discharge and at 90 days was 90% and 92%, respectively. Conclusion: Advanced age and comorbidities such as hypertension, diabetes, and dyslipidemia increase the risk of extracranial carotid artery stenosis and subsequent ischemic stroke. Patients undergoing extracranial carotid stenting had favorable clinical outcomes, with no mortality during treatment. A NIHSS low and early intervention within 14 days of stroke onset were associated with better clinical outcomes at discharge and at 90 days.
