Computed tomographic and Doppler sonographic correlations in patients with ischemic strokes

Full text: Introduction: Ischemic strokes (cerebral infarctions) constitute 80% of the acute disorders of the brain circulation. They most frequently occur in atherosclerosis of the extra- and intracranial vessels and/or arterial hypertension heart diseases (ischemic heart disease, rhythm and conductive disorders), cerebral vasculitis, blood diseases originating from hypercoagulability (thrombocytosis), etc. One of the well studied and adequately supported by documents risk factors for cerebral vascular disease (RF for CVD) are the asymptomatic carotid stenosis (ACS) and the symptomatic stenosis, especially the haemodynamically significant ones. Materials and methods: Two hundred twenty two patients with ischemic brain strokes originating from carotid stenosis, hypertension and heart diseases were studied. The correlation between the size and localization of the brain stroke was studied through computer tomography, while the grade of the carotid stenosis was determined with the help of Doppler sonography. Results and discussion: Significant correlations between the size and localization of the ischemic foci and the grade of the carotid stenosis in patients with brain stroke were found in a considerable number of patients. In most of the patients the electrocardiography tests showed the presence of heart diseases, a fact which gives evidence for the generalization of the vessel disorders in these patients. Conclusion: Our study confirmed the high diagnostic value of the combination of these two methods, on the one hand is sufficiently informative, on the other hand are generally available
