[The "no reflow" phenomenon in the cerebral cortex in the early postischemic period].

Experiments on white rats with clinical death due to blood loss were made to demonstrate the presence of the "no-reflow" focuses in the cerebral cortex in the first minutes of recirculation. The microcirculatory disturbances were functional in nature and were determined by the spasm of the small intracranial arteries, arterioles and precapillary sphincters.
