Cerebral aneurysm

The prognosis for a patient with a ruptured cerebral aneurysm depends on the extent and location of the aneurysm and the person's age, general health, and neurological condition. A formal comprehensive grading system has been published that incorporates age, aneurysm size, density of subarachnoid haemorrhage (if present), and clinical condition of the patient. This system predicts outcome ≥6 months after aneurysm treatment.[60]Ogilvy CS, Cheung AC, Mitha AP, et al. Outcomes for surgical and endovascular management of intracranial aneurysms using a comprehensive grading system. Neurosurgery. 2006;59:1037-1042. http://www.ncbi.nlm.nih.gov/pubmed/17143238?tool=bestpractice.com In particular, there is a significant correlation between the Hunt and Hess scale, the Fisher scale, and the patient's age on outcomes, regardless of treatment with clipping or coiling. Aneurysm size had less influence on endovascular outcomes than on surgical outcomes. Posterior circulation aneurysms fared worse than those in the anterior circulation.
