The Computational Fluid Dynamics Rupture Challenge 2013—Phase I: prediction of rupture status in intracranial aneurysms.
BACKGROUND AND PURPOSE Rupture risk assessment for intracranial aneurysms remains challenging, and risk factors, including wall shear stress, are discussed controversially. The primary purpose of the presented challenge was to determine how consistently aneurysm rupture status and rupture site could be identified on the basis of computational fluid dynamics. MATERIALS AND METHODS Two geometri...
متن کاملMind the gap: impact of computational fluid dynamics solution strategy on prediction of intracranial aneurysm hemodynamics and rupture status indicators.
BACKGROUND AND PURPOSE Computational fluid dynamics has become a popular tool for studying intracranial aneurysm hemodynamics, demonstrating success for retrospectively discriminating rupture status; however, recent highly refined simulations suggest potential deficiencies in solution strategies normally used in the aneurysm computational fluid dynamics literature. The purpose of the present st...
متن کاملInfluence of hemodynamic factors on rupture of intracranial aneurysms: patient-specific 3D mirror aneurysms model computational fluid dynamics simulation.
BACKGROUND AND PURPOSE Hemodynamics factors play an important role in the rupture of cerebral aneurysms. The purpose of this study was to evaluate the impact of hemodynamic factors on the rupture of the MANs with 3D reconstruction model CFD simulation. MATERIALS AND METHODS RDSA was performed in 9 pairs of intracranial MANs. Each pair was divided into ruptured and unruptured groups. The hemod...
متن کاملIntracranial Aneurysms: Wall Motion Analysis for Prediction of Rupture.
Intracranial aneurysms are a common pathologic condition with a potential severe complication: rupture. Effective treatment options exist, neurosurgical clipping and endovascular techniques, but guidelines for treatment are unclear and focus mainly on patient age, aneurysm size, and localization. New criteria to define the risk of rupture are needed to refine these guidelines. One potential can...
متن کاملIntracranial aneurysms: individualising the risk of rupture.
The decision of what to do with asymptomatic unruptured intracranial aneurysms is a fairly new problem. Although these aneurysms have been known to exist for centuries through autopsies and for several decades through catheter angiography, their true prevalence did not begin to emerge until the use of non-invasive angiograms became widespread in the recent past. Now we know that nearly 3% of th...
