METHODS: 328 patients with ischemic stroke were included in this study. Doppler ultrasound was used for evaluation of atherosclerosis in extracranial carotid arteries. The NASCET criteria were used to measure carotid stenosis. RESULTS: Ninety of 328 patients (27.4%) were found to have atherosclerotic plaques; 40 of these patients were women and 50 were men. Sixty-eight patients (20.7%) had artery stenosis 70% artery stenosis.
