Computational fluid dynamics (CFD) using porous media modeling predicts recurrence after coiling of cerebral aneurysms

OBJECTIVE This study aimed to predict recurrence after coil embolization of unruptured cerebral aneurysms with computational fluid dynamics (CFD) using porous media modeling (porous media CFD). METHOD A total of 37 unruptured cerebral aneurysms treated with coiling were analyzed using follow-up angiograms, simulated CFD prior to coiling (control CFD), and porous media CFD. Coiled aneurysms we...

Computational fluid dynamics analysis on recurrence of simple coiling intracranial aneurysms with remnant neck

Background: Hemodynamic factors are considered to play an important role in the initiation and recurrence of cerebral aneurysms. However, hemodynamic characteristics leading to the recurrence of aneurysms is not well recognized. This study analyzes the hemodynamics of simple-coiling and remnant-neck aneurysms, and discusses the impact of hemodynamic factors on the recurrence of cerebral aneurys...

Computational Fluid Dynamics (CFD) Modeling of Photochemical Reactors

Techniques of coiling cerebral aneurysms.

BACKGROUND More than 200 aneurysms have been coiled at the UIC Medical Center within the last 5 years. We describe in detail the technical factors that increase the chance of complete occlusion of a cerebral aneurysm with coils. Aneurysms selected for coiling have good geometry or are in a location that is difficult to reach surgically. Patients with medical conditions that preclude surgical tr...
