Etminan et al reported the Unruptured Intracranial Aneurysm Treatment Score (UIATS). One component identifies features favoring conservative management over repair. The numerous authors are from multiple institutions from around the world.
Patient selection: unruptured intracranial aneurysm
Patient parameters:
(1) life expectancy years
(2) comorbid conditions (may be multiple)
Treatment parameters:
(1) age-related risk
(2) aneurysm size-related risk in mm
(3) aneurysm complexity risk

total score =
= SUM(points for all of the parameters) + 5
Interpretation:
• minimum score: 6
• maximum score: 29
• If the score favoring repair exceeds the score favoring conservative therapy, then repair should be considered. Else consider conservative management.
