What are the chances of a 2cm calisfied splenic artery aneurysm growing or rupturing after being stable for 5 years?

By Cleveland clinic website: People with symptoms face an 80% chance of a rupture (compared to a 10% risk among people with no symptoms). By UPTODATE: the mean size of a ruptured splenic artery aneurysm is 3.5 cm and the mean size of a nonruptured artery splenic aneurysm is 2.2 cm. So if you are asymptomatic and aneurysm of 2 cm has been stable for 5 years I would say the risk is low. Good luck!
