Abstract
For pressure pulses to be transmitted to vital organ vascular beds, minimum loss through vascular branching junctions is necessary. Experimental measurements of pulse wave velocities and cross-sectional areas allowed branching reflections to be quantified. Wave reflections at normal aorto-iliac junction is minimal. Increased reflection occurs when the branch vessel is either narrowed or occluded. Also, geometric factors dominate over elastic factors in determining the amount of pulse wave reflections at the aorto-iliac junction.
摘要
为了使压力脉冲传输至重要器官的血管床，血管分支连接处的损失必须最小。对脉搏波速度和横截面积进行实验测量，从而能够对分支反射进行量化。正常主动脉-髂动脉连接处的波反射最小。当分支血管变窄或闭塞时，反射会增加。此外，在决定主动脉-髂动脉连接处脉搏波反射量时，几何因素比弹性因素更为重要。
