Method and apparatus for treating a patient sustaining an acute ischemic stroke in a brain having a blood circulatory system including a torcular Herophili (97) and adjoining transverse venous sinuses (96), includes steps for partially occluding the sinuses to partially obstruct venous blood drainage while permitting some antegrade venous blood flow from at least one of the sinuses. A flow of the patient's arterial blood is introduced into at least one of the sinuses to produce a continuous retrograde blood flow on the venous side of the brain.
