JNNP: Prevalence, predictor, and prognosis of occasional intracranial aneurysms in patients with suspected transient cerebral ischemic episodes (TIA) and mild stroke: a population-based study and systematic backtracking

Unbromed intracranial aneurysms (UIAs) are common occasional imaging manifestations, but little information is available for patients with transient ischemic episodes (TIA)/strokes.
UIA may occur more frequently due to common risk factors, but the risk of rupture can be reduced through enhanced secondary prevention.
this paper examines the prevalence and prognosis of UIA in patients with suspected transient isoemia attacks/minor strokes.
: All patients with suspected transient cerebral isoemia attacks (TIA) and non-invasive angiosis included in the Oxford Vascular Study (2011-2020).
authors identified the prevalence of occasional asymptomatic UIA and the subsequent risk of subcrystrial hemorrhage (SAH) through follow-up to intensive treatment and guideline-based monitoring/management.
authors also conducted a systematic review of UIA prevalence/prognosm in the TIA/stroke queue.
95 (4.7%) of the 2013 eligible patients had 103 previously unknown asymptomatic UIA.
women (OR 2.3, 95% CI 1.5-3.7), smoking (2.1, 1.2-3.6) and high blood pressure (1.6, 1.0-2.5) were independent predictive factors for UIA, with a prevalence rate of 11.1% among all three risk factors.
in an average of 4.5 years of follow-up, only one case of subcab bleeding occurred: 2.3 cases (95% confidence interval 0.3 to 16.6).
the authors identified 19 UIA studies in the TIA/Stroke Cohort (n-12,781), all of which had symptomatic cervical artery stenosis or severe acute stroke.
the combined average UIA prevalence rate for TIA/stroke patients was 5.1% (95% CI is 4.8-5.5) and the incidence rate of SAH was 4.6 (95% CI was 1.9-11.0).
5% of confirmed TIA/mild stroke patients may have a higher UIA prevalence rate than the general population.
, however, the risk of SAH is low in intensive care and guidance-based management/monitoring.
