Two dimensional steady flow calculations in computational regions obtained from radiographs of human aortic bifurcations correlate well with unsteady measurements of wall shear in flow-through casts of the same vessels. The results suggest that wall slope may be an important factor affecting the variability of shear along the medial walls of this arterial segment. If extremes of shear stress promote atherogenesis, then variations in the curvature of the proximal iliac arteries may affect the susceptibility of these vessels to vascular disease on their medial aspect.
从人体主动脉分叉的X光片获得的计算区域内的二维稳态流动计算结果，与相同血管的流通铸型中壁面切应力的非稳态测量结果具有良好的相关性。结果表明，壁面斜率可能是影响该动脉段内侧壁切应力变化的一个重要因素。如果切应力极值会促进动脉粥样硬化的发生，那么近端髂动脉曲率的变化可能会影响这些血管内侧对血管疾病的易感性。
