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.
