説明
Three-dimensional numerical simulation is performed of pulsatile flow around a tori-modeled stent inserted into parent artery below a neck of sidewall aneurysm. When blood flow in the aneurysm is suppressed by the stent, thrombus is generated in the aneurysm resulting in prevention of development and rupture of the aneurysm. The mechanism is clarified which the flow is induced in the aneurysm even when the aneurysm neck is covered by fluid-dynamic obstacles of stent filaments. The averaged maximum Reynolds number is chosen as 250 and Womersley number as 2.7. It is shown that flow-inducing sources are pressure difference between proximal and distal sides in the aneurysm neck and kinetic energy flowing into the aneurysm at the proximal side whose direction is turned from axial to radial directions and whose magnitude is reduced due to impingement of boundary-layer flow in the parent artery. Possibility of the thrombus formation on the aneurysm wall is evaluated using the shear rate.
