2024年7月31日 · The modified Fisher scale is a method for radiological grading subarachnoid hemorrhage (SAH) secondary to intracranial aneurysm rupture, assessed on the first non-contrast CT. It was modified from the original Fisher scale in 2006 1 to account for patients with thick cisternal blood and concomitant intraventricular hemorrhage.

States severity of SAH based on amount and type of blood on CT with associated vasospasm risk. This scale only applies to aneurysmal subarachnoid hemorrhage (aSAH). Thin SAH is classified as < 1mm in depth. Thick SAH is classified as ≥ 1mm in depth.

Rates risk of vasospasm in aSAH based on amount and distribution of blood on CT. This scale only applies to aneurysmal subarachnoid hemorrhage (aSAH). We recommend using the Modified Fisher Grading Scale based on more recent studies. Clinician must be able to identify subarachnoid hemorrhage (SAH) and major neuroanatomical landmarks on head CT.

2023年8月10日 · Nontraumatic subarachnoid hemorrhage (SAH) is most commonly caused by ruptured saccular aneurysms. SAH is often a devastating event with substantial mortality and high morbidity among survivors. The appropriate therapy for …

2024年7月7日 · validated to predict likelihood of vasospasm, minimal inter-observer variability. predicts risk of delayed cerebral ischemia, combines additive risk from SAH and IVH. Claassen J, Vu A, Kreiter KT. Effect of acute physiologic derangements on outcome after subarachnoid hemorrhage. Critical care medicine. 32 (3):832-8. 2004. [PMID 15090970]

2015年6月30日 · Grade 4, which represents a range of GCS scores between 7 and 12, includes a group of patients who may have widely different outcomes. Another method of scoring SAH severity (with implications for vasospasm) is the Fisher scale, which was introduced in 1980. Essentially, this scale relates the amount of blood to the risk of vasospasm.

2021年12月2日 · Her headache is significantly more severe than her migraine headaches. Her symptoms began approximately 2 hours ago after she was lifting heavy weights. She denies …

We performed a retrospective review of 94 consecutive cases of spontaneous SAH presenting within 72 hours of onset. SAH was categorized into five grades based on the short-axis thickness of SAH in 20 intracranial cisterns measured on the axial, coronal, and sagittal planes.

Purpose—The aim of this guideline is to present current and comprehensive recommendations for the diagnosis and treatment of aneurysmal subarachnoid hemorrhage (aSAH). Methods—A …

2024年6月10日 · The Hunt and Hess scale describes the clinical severity of subarachnoid hemorrhage resulting from the rupture of an intracerebral aneurysm and is used as a predictor of survival. It was first described in 1968 by two neurosurgeons from Ohio, USA:
