Human umbilical cord veins and arteries were used as arterial substitutes in baboons. Eight of ten vein implants in the aortic position maintained patency up to 12 weeks. However, ectasia appeared after one week, and aneurysms developed after three weeks. All eight cord artery implants became occluded after implantation. Althogh it is technically feasible to use cord vessels as arterial substitutes, structural and immunologic modifications will be required to achieve satisfactory results on a practical basis following long term implantation.
