对60例成人标本观测发现,腹主动脉叉左右侧分离角、曲率及髂总动脉口径有显著差异,为非对称性分叉管。血流动力学分析认为,其几何解剖特征可能是叉区动脉粥样硬化病变不对称分布的重要因素。
The observation of 60 adult specimens found that the separation angle and curvature of the left and right sides of the abdominal aorta and the diameter of the common iliac artery were significantly different and were asymmetrical furcations. Hemodynamic analysis suggests that the geometric anatomical features may be an important factor in the asymmetric distribution of atherosclerotic lesions in the cross-region.
