Jun 18, 2015 · Since the last US consensus statement was published in 2000, the International Study of Unruptured Intracranial Aneurysms (ISUIA) 4 has published prospective data regarding a large cohort of patients with UIAs, stratified by size.

Dec 10, 1998 · In the prospective component, we assessed treatment-related morbidity and mortality in 1172 patients with newly diagnosed unruptured intracranial aneurysms.

Jul 12, 2003 · Investigators from the International Study of Unruptured Intracranial Aneurysms aimed to assess the natural history of unruptured intracranial aneurysms and to measure the risk associated with their repair.

May 12, 2021 · Unruptured intracranial aneurysms (UIAs) are commonly acquired vascular lesions that form an outpouching of the arterial wall due to wall thinning. The prevalence of UIAs in the general population is 3.2%.

Jul 12, 2003 · Unlike previous studies of unruptured intra-cranial aneurysms, including ISUIA, 1 this study provides natural history data from prospec-tively identified patients, thereby eliminating several potential selection biases related to retrospective patient identification, including retrospective records review and availability of hard copy ...

Oct 31, 2000 · Although the prevention of hemorrhage has been advocated as the most effective strategy aimed at lowering mortality rates, 6 the optimal management of patients with unruptured intracranial aneurysms (UIAs) remains controversial.

Unruptured intracranial aneurysms (UIA) are a common finding, occurring in about 2% of the population, making them very likely to be seen by most practitioners, and present a challenge in the recommendations for optimal management and screening.

Sep 2, 2014 · We divided the current guideline for ruptured intracranial aneurysms (RIAs) and unruptured intracranial aneurysms (UIAs). The guideline for RIAs focuses on diagnosis and treatment.
