PHASES score: 0   |   5-year rupture risk: 0%

Size of aneurysm?
Earlier subarachnoid hemorrhage from another aneurysm?
Site of aneurysm?

Background: The PHASES Calculator combines patient data from six prospective cohort studies and estimates a 5 year cerebral aneurysm rupture risk. While aneurysm growth and rupture risk are not constant over time, this educational tool can help aid in patient discussions.
