The authors present analytical and numerical approaches of the deformation of venous and arterial vessels vasa vasorum. An elastic behaviour of the vessel wall is supposed. It is shown that a normal range of intraluminar pressure induces a small deformation in the vasa vasorum in arteries. According to the nonlinear elastic behaviour, a larger deformation is induced in venous vasa vasorum is rapidly obtained. Increased pressure has serious consequences, especially on the flow in vasa vasorum and induces decrease of oxygen transport. This phenomenon could be one of the generating factors of atherogenesis and ischemia.
作者介绍了血管滋养管中静脉和动脉血管变形的分析和数值方法。假定血管壁具有弹性行为。结果表明，管腔内压力的正常范围会在动脉血管滋养管中引起小变形。根据非线性弹性行为，静脉血管滋养管中会迅速产生较大变形。压力升高会产生严重后果，尤其是对血管滋养管内的血流，并导致氧气输送减少。这种现象可能是动脉粥样硬化和局部缺血的成因之一。
