Abstract

To analyze the co-occurrence of atherosclerotic lesions in CT angiograms of extra and intracranial arteries in patients with cerebral circulation insufficiency. 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. Intracranial CTA results were compared to those of the control group, which consisted of 34 subjects asymptomatic of cerebral circulation insufficiency. The usefulness of various data reconstruction techniques (MIP and MPR vs. MIP only) for the evaluation of intracranial stenosis was subjected to independent analysis by two radiologists. Concomitant occurrence of extra-and intracranial lesions was diagnosed in 56% of patients examined. A statistically significant correlation was found between the degree of stenosis at both levels under consideration (chi2=81.452; p<0.00001; contingency coefficient CC=0.733). A significant correlation was found between the development of clinical symptoms and the severity of extra and intracranial stenosis. The consistency between % representation of CTA-detected intracra...Continue Reading
