Why Is ABI Effective in Detecting Vascular Stenosis? Investigation Based on Multibranch Hemodynamic Model
Figure 7
Changes of ABI value with stenosis increased from 0% to 80% at 4 arteries, respectively. (a) variation tendency of ABI with femoral stenosis; (b) variation tendency of ABI with popliteal stenosis; (c) variation tendency of ABI with posterior tibial stenosis; (d) variation tendency of ABI with brachial stenosis. The dotted line in each figure represents the evaluation standards of normal ABI (0.91~1.30) which is used as the threshold for stenoses diagnosis in clinical data.
