Delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage-areas at risk

Delayed cerebral ischemia is a major neurological complication of aneurysmal subarachnoid hemorrhage. Its unpredictable course and potentially unfavorable outcome draw attention to clinicians to improve the methods for its prediction, prevention, and diagnosis. The computed tomography perfusion (CTP) technique of the brain is one of the promising methods for revealing brain areas endangered by cerebral vasospasm and delayed cerebral ischemia.
