Аннотация
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.
