ISUIA Trial

Last edit by on

The ISUIA Trial was published in The Lancet in 2003 and investigated the management of unruptured intracranial aneurysms in a total of 4060 patients enrolled in the study from 61 centers1.

Cumulative 5-year rupture risk

ISUIA rupture risk
Group 1 = Without a history of subarachnoid hemorrhage. Group 2 = With a history of subarachnoid hemorrhage. Figure adapted from the original publication of the ISUIA study.

Interpretation by the study authors

Many factors are involved in management of patients with unruptured intracranial aneurysms. Site, size, and group specific risks of the natural history should be compared with site, size, and age-specific risks of repair for each patient.2
