title: Vasospasm and cerebral infarction following isolated intraventricular hemorrhage.
abstract: BACKGROUND
  Cerebral arterial vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is an important cause of delayed neurologic deterioration. Vasospasm following isolated intraventricular hemorrhage (IVH) is less common. Accepted predictors of vasospasm following SAH include poor Hunt-Hess grade, elevated transcranial Doppler velocities, and the thickness of cisternal blood on neuroimaging [1, 2]. The role of intraventricular hemorrhage in vasospasm is more controversial.
  
  
  METHODS
  Case report and review of the literature.
  
  
  RESULTS
  A 41-year-old woman developed symptomatic delayed vasospasm 10 days following isolated IVH due to the rupture of an arteriovenous malformation (AVM).
  
  
  CONCLUSIONS
  Intraventricular hemorrhage can independently cause significant delayed vasospasm. Possible mechanisms are described.
