Clinico radiological profile of cerebral venous sinus thrombosis with prognostic evaluation using MR sequences

Abstract

Introduction: The cerebral venous system consists of dural venous sinuses, superficial cortical veins, deep medullary and subependymal veins [1]. Cerebral veins contain about 70% of the total cerebral blood volume but CVT occurs about thousand times less often than arterial stroke. Arterial and venous stroke cause different neurological deficits and occur in people of different ages. About half of the patients with an arterial stroke are older than 75 years, whereas CVT most often affects young adults and children. Any pathology that alters the Virchow's triads of flow vessel wall and fluid blood physiology can cause thrombosis [2].
