Cerebral circulation insufficiency - correlation of CTA-visualized atherosclerotic lesions in extra- and intracranial arteries.

Background: To analyze the co-occurrence of atherosclerotic lesions in CT angiograms of extra and intracranial arteries in patients with cerebral circulation insufficiency.

Material/methods: Extra-and intracranial CTA was performed in 70 patients with symptoms of cerebral circulation insufficiency. Co-occurrence of atherosclerotic lesions at both levels and correlation between the degree of atherosclerosis and sex, age, and clinical symptoms were evaluated.
