Hemostasis in peripheral vascular surgery is made more difficult by the need for direct arterial and arterial graft suturing as well as by systemic anticoagulation to prevent thrombosis during periods of vascular occlusion. Polytetrafluorethylene (PTFE) is one of the most frequently used graft materials for vascular replacement or bypass in the case when no autologous venae are available (1). However, the insufficient elasticity of PTFE and its porosity promote the development of suture hole bleeding (2,3) which can cause considerable loss of blood and prolongation of operations (2).
