When a catheter is inserted through an artery, the wall shear stress increases and the secondary flow exhibits an increased number of instantaneous vortices. These effects become more evident when the annular gap between the catheter and the artery becomes more narrow. Accordingly it is suggested that these factors may affect the preferential distribution of the atheromatous plaques at the sites of the wall with an increased permeability.
当通过动脉插入导管时，壁面剪应力增加，二次流表现出更多数量的瞬时涡旋。当导管与动脉之间的环形间隙变得更窄时，这些影响会变得更加明显。因此，有人提出这些因素可能会影响动脉粥样硬化斑块在渗透性增加部位的优先分布。
