An overview of intracranial aneurysms

McGill Journal of Medicine, 2020
Intracranial aneurysms are relatively common, with a prevalence of approximately 4%. Unruptured aneurysms may cause symptoms mainly due to a mass effect, but the real danger is when an aneurysm ruptures, leading to a subarachnoid hemorrhage.

Accuracy of Length of Virtual Stents in Treatment of Intracranial Wide-Necked Aneurysms. [PDF]

, 2019
Background and purposePrecise stent deployment is important for successful treatment of intracranial aneurysms by stent-assisted coiling (SAC). We evaluated the accuracy of virtual stents generated using commercial stent planning software by comparing ...

An automated multiscale ensemble simulation approach for vascular blood flow [PDF]

, 2015
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, are known to be a major factor in the risk of aneurysm formation and ...

Hemodynamics in Cerebral Aneurysms and Parent Arteries With Incompletely Expanded Flow Diverter Stents

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 4, April 2025.
Incomplete stent expansion (IncompSE) during flow diverter stent (FDS) deployment may lead to unfavorable hemodynamic changes, increasing risks of complications and incomplete aneurysm occlusion. Using computational fluid dynamics (CFD), we analyzed three basic aneurysm models under various incompSEs. IncompSE resulted in higher volume flow, wall shear

The unruptured intracranial aneurysm treatment score A multidisciplinary consensus [PDF]

, 2015
Objective: We endeavored to develop an unruptured intracranial aneurysm (UIA) treatment score (UIATS) model that includes and quantifies key factors involved in clinical decision-making in the management of UIAs and to assess agreement for this model ...

Endovascular Treatment of Unruptured Intracranial Aneurysms [PDF]

Interventional Neuroradiology, 2011
We report the clinical and angiographic results of endovascular treatment of unruptured intracranial aneurysms. Over a three-year period, 80 unruptured aneurysms in 74 patients were electively treated with endovascular management. One aneurysm was diagnosed during investigations for a second ruptured aneurysm, 54 aneurysms were incidentally ...

Two‐Sample Mendelian Randomization Analyses Identified Lipid Species Associated With Intracranial Aneurysm Formation

Brain and Behavior, Volume 15, Issue 3, March 2025.
This study investigates the causal relationship between lipid variants and unruptured intracranial aneurysm (uIA) formation using Mendelian randomization. Seven lipid species were identified as risk factors or protective agents for uIAs, offering insights into potential new biomarkers for IA risk assessment and treatment.

Bleb formation in small unruptured intracranial aneurysm as a predictor of early rupture [PDF]

, 2018
Small unruptured aneurysms are thought to have a low risk of rupture, but the management of such lesions is still controversial. A 73-year-old man with a small anterior communication artery aneurysm, 4 mm in diameter, while on follow-up, developed an ...
