Simultaneous cerebral arterial and venous thrombosis.

Simultaneous thrombotic occlusion of cerebral arterial and venous systems in the same individual is rare. Three patients of stroke in whom autopsy revealed co-existing arterial and venous infarctions, major arterial occlusion (vertebral 1, internal carotid 1) and dural sinus and cortical vein thrombosis are reported. Role of infarcted brain, haemorrheological factors and alcohol in the pathogenesis of this rare event is highlighted.
