Extra-Intracranial Anastomosis Operation Associated with Hyperbaric Oxygenation in the Treatment of Completed Stroke

Abstract

A completed stroke (CS) is most frequently due to an occlusive vascular lesion resulting in cerebral hypoxia, ischemia, or a combination of these.³ Whether in such post stroke states the neurologic disorder is due to reversible or irreversible neuronal alterations cannot be predicted. In case the neurons have lost their function but are still alive, it appears reasonable to assume that improving the oxygenation of the brain tissue either by increasing the oxygen concentration in the arterial blood or by in-creasing the cerebral blood supply may result in an improvement of the neurologic deficit.
