The most widely accepted classification of ischemic stroke is based on TOAST criteria which divides ischemic stroke into five categories, namely--large artery atherosclerosis, cardioembolism, small vessel occlusion (lacunar infarction), undetermined etiology and multiple possible etiologies [5,6] Another method of classification is modified Oxfordshire method, based on the anatomic distribution of infarcts-- total anterior circulation infarcts, partial anterior circulation infarcts, posterior circulation infarcts, watershed infarcts, centrum ovale infarcts and lacunar infarcts.
Centrum ovale infarcts: subcortical infarction in the superficial territory of the middle cerebral artery.
