A computational method for calculating the dynamic distensibility of the vessel wall in vivo, developed on the basis of the pressure pulse transmission, is proposed. Distensibilities of descending thoracic aorta, abdominal aorta, and femoral artery in normal dogs, and of femoral artery of a typical dog under the action of vasoactive drugs, have been calculated. In femoral artery it is compared with the values of the diameter change/pressure change. Comparison of the results clearly indicate the feasibility of the proposed method. The order of distensibility found is: descending thoracic aorta greater than abdominal aorta greater than femoral artery.
提出了一种基于压力脉冲传播在体内计算血管壁动态扩张性的计算方法。已计算出正常犬降主动脉、腹主动脉和股动脉以及一只典型犬在血管活性药物作用下股动脉的扩张性。在股动脉中，将其与直径变化/压力变化值进行了比较。结果比较清楚地表明了所提方法的可行性。所发现的扩张性顺序为：降主动脉大于腹主动脉大于股动脉。
