  • 3D Hemodynamic Numerical Simulation of Carotid Artery Aneurysm Before and after Surgery Based on CT Date

    Hemodynamic situation is an important factor of recurrence of postoperative carotid artery aneurysm. In order to investigate the hemodynamic factors of postoperative carotid artery aneurysm affect carotid artery aneurysm recurrence, we established a 3D finite element carotid artery aneurysm for the preoperative and postoperative periods using the three-dimensional reconstruction techniques. And then we measured the hemodynamic factors of carotid artery aneurysm of preoperative and postoperative by the finite element method. The carotid artery aneurysm model has an accurate and realistic shape; the pressure of the recurrence of aneurysm was reduced significantly after surgery,wall shear stress increased significantly at residual neck, and blood flow velocity increased significantly, which will increase the risk of recurrence. The hemodynamic analysis provides a reference for development of aneurysm clinical treatment programs and prevention of recurrence.
