How is the risk of aneurysm calculated in ISUIA?
How is the risk of aneurysm calculated in ISUIA?
In the ISUIA aneurysm calculator, the figures returned under 5 year rupture risk reflect those provided in the ISUIA table. Based on this table, the annual risk of rupture was calculated by simply dividing this number by five, giving identical figures to those reported by da Costa et al in their 2004 Neurogurgical Focus article.
What kind of aneurysm balloons out the side of the artery?
Fusiform aneurysm. A fusiform aneurysm balloons or bulges out on all sides of the artery.
What’s the difference between small and large aneurysms?
The infection weakens the artery wall, causing a bulging aneurysm to form. Aneurysms are also classified by size: small, large, and giant. Small aneurysms are less than 11 millimeters in diameter (about the size of a large pencil eraser). Large aneurysms are 11 to 25 millimeters (about the width of a dime).
Why are phase aneurysms removed from the cohort?
Most importantly, some patients in these studies had their aneurysms treated during follow-up due to an increase in size or the development of symptoms. The removal of these high-risk patients from the cohort means that overall rupture risk may be somewhat higher than indicated in ISUIA, UCAS or PHASES.
What do you need to know about the NEJM?

Is there an international study of unruptured aneurysms?
Investigators form the International study of Unrupted intracranial Aneurysms aimed to asses the natural history of unrupted Intracranial aneurysms and to measure the risk associalted with the repair. Centres in the USA, Canada, and Europe enrolled patients for prospective assessment of unruptured aneurysms.
