title: Angiographic patterns of carotid ischemic cerebrovascular disease in Saudi Arabia.
abstract: The angiographic findings in 100 Saudi patients with carotid ischemic cerebrovascular disease (CVD) (transient ischemic attacks (TIA) or strokes) were retrospectively reviewed. These patients were representative of all patients with similar disorders in the terms of sex, frequency of diabetes mellitus and ischemic heart disease. They were, however, significantly younger, smoked more, had more cervical bruits and less atrial fibrillation. Analysis of the data showed that a significant stenosis (> 70%) of the carotid artery origin was found only in 12% of TIA cases, 4% in the lacunar infarction cases and 6% of the large infarction cases on the symptomatic side and only in one case of TIA in the asymptomatic side. These frequencies were significantly lower than those found in similar studies performed in western countries. This study suggests that stenoses and occlusions of extracranial carotid artery plays a smaller role in the pathogenesis of ischemic CVD in Saudis than in Caucasians. The low consumption of cigarettes among elderly and females may be one of the explanations.
