Abstract

Objective To further explain the blood flow characteristics of artery dissection by numerical simulation. Methods The CT (Computed Tomography) scan results of artery dissection were transformed into three-dimensional flow field in CFD(Computational Fluid Dynamics) software to build Lagrange multiphase flow simulation containing red blood and plasma by MIMICS (Materialise's interactive medical image control system). Results Vortex appears in the proximal end of false lumen, the inlet of false lumen and it's opposite experience relatively strong wall share stress, pressure differ between the two sides of the membrane, and is bigger in the distal end of false lumen, The distribution of red blood cells is uneven. Conclusions Arterial dissection reduces the amount of red blood cells in the blood ?due to the wall share stress and pressure, proximal end of false lumen damage easily?holes appear on the membrane beside branch arteries and balance pressure and flow?the arterial dissection is prone to thrombosis.
