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.
引言
本文报告了一例在动脉瘤破裂修复术后接受“三高”（高血压、高血容量和血液稀释）治疗的患者，其计算机断层扫描（CT）灌注显示为后部可逆性脑病综合征。
病例报告
“三高”疗法用于术后治疗血管痉挛，通过维持脑灌注压来预防中风和出血。
讨论
一个潜在的并发症包括脑血管自动调节功能障碍引起的血管源性水肿。CT灌注可以检测到这些血流动力学变化所导致的脑血流量和血容量的改变。
