Numerical simulations of stenosed femoral artery with symmetric 2‐way bypass graft

Abstract

The numerical simulation of the conventional 1‐way bypass graft and the presented 2‐way bypass graft used in the stenosed femoral arteries were completed. Purpose of the present study was to ascertain whether the modified geometry configuration of 2‐way bypass graft could improve the flow conditions of femoral bypass graft. The physiological flows in 1‐way and 2‐way models were simulated with finite element method under the same calculation conditions. Comparisons were made between the hemodynamics of 1‐way and 2‐way models. The results suggested that 2‐way bypass graft could result in more favorable and regular flow conditions than 1‐way bypass graft, and could decrease the probability of intimal hyperplasia, restenosis and surgery failure in femoral bypass graft.
