Diabetes deteriorates atherosclerotic changes in the arteries. The aim of the study was to assess the prevalence and localization
of stenotic atherosclerotic lesions of the internal carotid artery (ICA) in patients with diabetes. A prospective
analysis of angiography findings was carried out in 150 diabetic and 150 non-diabetic patients with symptoms of cerebral
ischemia using double-blind angiogram readings by two independent investigators. The degree of stenosis was determined
using the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Stenoses of the
proximal arterial segment accounted for the majority of extracranial ICA stenoses, being more frequent in diabetic (left
ICA 50.7%, right ICA 58.0%) than in the non-diabetic patients (left ICA 29.3%, right ICA 32.7%). Diabetic patients revealed
a more significant rate of unilateral tandem ICA stenoses (14.0–21.3%), as well as a statistically significantly
higher prevalence of intracranial ICA stenoses (left ICA 24.0% and right ICA 17.3%) than did non-diabetic patients (left
and right ICA 3.3% each). Our results confirm that there is a morphological basis in ICA for increased incidence of ICA
lesions in patients with diabetes as compared to those without it. Data on the incidence of stenotic ICA lesions in diabetes
suggest the importance of assessing overall ICA status using digital subtraction angiography. Such an assessment is a
precondition for an optimal therapeutic approach, especially in diabetic patients who are at an increased risk of cerebrovascular
