BACKGROUND: Rupture risk of unruptured intracranial aneurysms (UIAs) has been
investigated in studies observing the natural history of this condition. Such studies have …

Background and Purpose—Our aim was to define for the first time the lifelong natural course
of unruptured intracranial aneurysms (UIAs) and identify high-risk and low-risk patients for …

Introduction Unruptured intracranial aneurysms (UIA) are common in the adult population,
but only a relatively small proportion will rupture. It is therefore essential to have accurate …

Background Management of incidental unruptured intracranial aneurysms (UIAs) remains
challenging and depends on their risk of rupture, estimated from the assumed prevalence of …

OBJECTIVE To test the hypothesis that unruptured aneurysms have different characteristics
and risk factor profiles compared to ruptured aneurysms. METHODS We recruited patients …

Objective We conducted a retrospective cohort study to elucidate the natural course of
unruptured intracranial aneurysms (UIAs) at a single institution. Methods Data from patients …

Background and Purpose—We wanted to evaluate potential risk factors for unruptured
intracranial aneurysms (UIAs) and aneurysmal subarachnoid hemorrhage (aSAH) in a large …

Morita and colleagues present a very interesting paper about an important topic that may be
particularly pertinent in Japan given that some of the highest incidence rates for …

Background The incidence of unruptured intracranial aneurysms (UIAs) and the current
public health impact may be higher than that reported in previous studies owing to an …

We thank Drs Kirchoff-Torres and Labovitz for their interest in our article. 1 The authors fear
that the presented results may be overgeneralized. We share the view that the applicability …
