Posterior reversible encephalopathy syndrome on computed tomography perfusion in a patient on "Triple H" therapy.
Overview
abstract
INTRODUCTION: This article reports a case of posterior reversible encephalopathy syndrome on compyted tomography (CT) perfusion in a patient on "Triple H" (hypertension, hypervolemia, and hemodilution) therapy following aneurysmal rupture repair. CASE REPORT: "Triple H" therapy is used in the postoperative course for treatment of vasospasm to prevent stroke and hemorrhage by maintaining cerebral perfusion pressure. DISCUSSION: A potential complication includes vasogenic edema from dysfunction of cerebral blood vessel autoregulation. CT perfusion can detect alterations in cerebral blood flow and volume caused by these hemodynamic changes.
