OBJECTIVE Pathophysiological differences that underlie the development and subsequent
growth of multiple aneurysms may exist. In this study, the authors assessed the factors …

Background The literature on multiple intracranial aneurysms (MIA) in patients with
aneurysmal subarachnoid hemorrhage (aSAH) focuses largely on risk factor analysis and …

Background: The risk of aneurysmal rupture is dependent upon numerous factors, however,
there are inconsistencies in the results between studies, which may be due to confounding …

Objective Multiple factors are known to influence outcomes in single-aneurysm
subarachnoid hemorrhage, such as Hunt and Hess (H&H) grade, hypertension, etc. We …

BACKGROUND AND PURPOSE: In patients with SAH with multiple intracranial aneurysms,
often the hemorrhage pattern does not indicate the rupture source. Angiographic findings …

Object This study was performed to investigate the risk factors related to the growth of small,
asymptomatic, unruptured aneurysms in patients with no history of subarachnoid …

Object The authors of recent reports have suggested that smaller aneurysms are associated
with more extensive sub-arachnoid hemorrhage (SAH), which could potentially presage …

OBJECTIVE: Intracranial aneurysm size is an important determinant of risk of rupture and
outcome after rupture. Risk factors influencing aneurysm formation and growth are not well …

Background A community-based study was conducted to estimate the incidence rates of
multiple aneurysms and to investigate the factors related to multiplicity. Method The subjects …

BACKGROUND Prospective studies of unruptured aneurysms have shown very low rates of
rupture for small aneurysms (< 10 mm) and suggested that the risk of treatment outweighs …
