The experimental strategies in the study of ischemic stroke

Abstract

Literature data and own experience in the studies of experimental stroke methodology are reviewed. Advantages and disadvantages of the common models of focal ischemia used in the laboratory practice are discussed in details. The advantages of the filament occlusion of the middle cerebral artery in rats as the most adequate model of human stroke are substantiated. The authors suggest a modification of this variant using an additional coagulation of the pterygopalatine artery that allows the exclusion of the retrograde and collateral blood flow into the inner carotid artery after ligation of the common and external carotid arteries.
