项目摘要
The purpose of the present study is to elucidate the role of hemodynamics in atherosclerosis by experimental induction of atherosclerotic plaque in the swine carotid artery. Complex atherosclerotic plaque was successfully induced in the lesion distal to surgical partial ligation. Systolic and diastolic flow velocity were obtained with phase contrast sequence in 3.0 Tesla MRI. Wall shear stress was calculated with the obtained dataset. Shear stress was maintained high in the lesion distal to surgical partial ligation due to unidirectional jet flow. By contrast, in the lesion proximal to ligation, shear stress was found to oscillate during cardiac cycle. Low wall shear stress may contribute to plaque formation in this animal model.
本研究的目的是通过实验诱导猪颈动脉中的动脉粥样硬化斑块来阐明血流动力学在动脉粥样硬化中的作用。在手术部分结扎远端的病变中成功诱导了复杂的动脉粥样硬化斑块。收缩期和舒张期流速通过 3.0 特斯拉 MRI 中的相差序列获得。使用获得的数据集计算壁剪应力。由于单向射流,手术部分结扎远端病变处的剪切应力保持较高。相比之下,在结扎附近的病变中,发现剪切应力在心动周期期间振荡。低壁剪切应力可能有助于该动物模型中斑块的形成。
