Impaired Glymphatic Perfusion After Strokes Revealed by Contrast-Enhanced MRI

Abstract

SAH and acute ischemic stroke significantly impair the glymphatic system perfusion. In these contexts, injection of tissue-type plasminogen activator either intracerebroventricularly to clear perivascular spaces (for SAH) or intravenously to restore arterial patency (for ischemic stroke) may improve glymphatic function.
