Prostheses, Blood Vessel, Artificial

Definition : Vascular grafts of synthetic (artificial polymers) origin that are intended to replace, bypass, or shunt a patient's diseased or injured blood vessel. These grafts are typically made of woven or knitted polyethylene terephthalate (Dacron) or polytetrafluoroethylene fabrics. Synthetic grafts are best suited for large diameter (more than 10 mm), high-flow vessel replacement such as aortoiliac artery reconstruction and for hemodialysis access and extra-anatomic bypass grafting. Synthetic vascular grafts are used in many vascular procedures (e.g., femoral popliteal, axilloaxillary artery bypass) except those involving the coronary arteries.
