Posterior reversible encephalopathy syndrome on computed tomography perfusion in a patient on "Triple H" therapy.

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.
