We encountered an unusual disruption of an expanded polytetrafluoroethylene (EPTFE) axillofemoral bypass graft apart from that anastomoses. We suspected the possible robe of the physical effects of body movement provoking the disruption of the axillofemoral bypass graft and therefore examined the physical effect of body movement on the axillary-to-femoral artery graft in 15 healthy men. At the lower part of the graft, the physical effect was significantly stronger. The disruption of this axillary-to-femoral artery graft was associated with the physical effect of body movement.
