Computational Modeling of Cerebral Aneurysm Coil Embolization

Coil embolization involves treating cerebral aneurysm from the inside out, whereby metallic coils are placed into the aneurysm to induce thrombosis of the lumen and eliminate the risk of rupture and hemorrhage. However a significant number of aneurysms remain incompletely occluded and recurrences are expected in the range of 11-36% after coil embolization depending on the degree of filling achieved. Our laboratory has developed computational tools to study how the coil thrombus mass (CTM) also known as coil packing density (CPD) after coil embolization influences the intracranial aneurysm wall stress at different degrees of coil filling.
