In assessing patients with a proven aneurysmal SAH, not only the clinical grading is important, but also the amount of subarachnoid (and/or intracerebral) blood. A reliable and universally used …

Jun 30, 2015 · Another method of scoring SAH severity (with implications for vasospasm) is the Fisher scale, which was introduced in 1980. Grade 1 - no haemorrhage; Grade 2 - SAH less …

The Fisher grading system uses CT-findings within 5 days of onset of a subarachnoid haemorrhage to evaluate risk of vasospasm. It looks primarily at amount and distribution of …

The Fisher grade, developed in 1980, is commonly used to predict the risk of cerebral vasospasm after subarachnoid hemorrhage (SAH) based on the amount of blood shown on initial CT...
