Management decisions regarding cerebrovascular disease are complex, and must be made by the patient and their family under guidance of an expert neurovascular physician. (© Babak S. Jahromi, 2020)

Aneurysm Rupture Risk

Adapted from: Greving et al (2014). Development of the PHASES score for prediction of risk of rupture of intracranial aneurysms: a pooled analysis of six prospective cohort studies. Lancet Neurol. 13(1):59-66

WARNING: Most included cohorts were highly selected and had only short follow up. Results may therefore not reflect the true natural history of an unselected population, and stand in contrast to the smaller size of most ruptured aneurysms.
