A NEW VIRTUAL COILING METHOD AND ITS USE IN EVALUATION OF COMBINING COILING AND FLOW-DIVERSION TREATMENT IN A PATIENT-SPECIFIC ANEURYSM
Printer-friendly versionPDF version

A new realistic finite element method (FEM) based endovascular coil deployment technique was developed to explore the hemodynamic modifications of coiling in addition to flow diverter (FD) treatment. A patient-specific internal carotid artery aneurysm was used as a test case, and a single flow diverter was deployed using a previously developed method , along with several coils using the new method. Results showed fluctuations in hemodynamic parameters at low packing densities (1-3 coils) which are unexpected. At high packing density however (6 coils), results were consistent with expectations. These results suggest that adding coils at low packing densities to FD treatment may not cause significant additional flow reduction into the aneurysm sac, but may provide a scaffold for aneurysmal thrombus formation.
