Use of umbilical vein graft as an arterial substitute.
Seventy reconstructions, 14 to the popliteal artery above the knee, 40 to the popliteal artery below the knee, and 16 to the tibioperoneal arteries were performed with the Dardik umbilical vein graft tanned in glutaraldehyde. Indications for use included absence of or inadequate saphenous veins, or for expediency during emergency or complex procedures. The cumulative patency rate (calculated by the life table method) for the total group was 77% at 18 months. The failures are further analyzed according to the type of procedure, the grade of disease, and the distal runoff vessel. Early failures were attributed primarily to poor runoff and not to intrinsic properties of the graft. Our overall experience with the umbilical vein graft has been good. Further long-term follow-up is necessary.
