The development of suitable homograft material and plastic prostheses has popularized arterial replacement procedures for the relief of major arterial occlusive disease in the extremities. Difficulties in storage and procurement of arterial homografts have led many surgeons to adopt the use of plastic prostheses as the material of choice. In addition, there have been difficulties with the homografts, including two reports of aneurysm formation in the femoral arterial replacements.1
Polyethylene (Dacron) and polytetrafluoroethylene (Teflon) are preferred by most surgeons.2 Some experimental data indicate that polytetrafluoroethylene is the superior synthetic.3 Having used polyethylene initially, woven polytetrafluoroethylene was chosen as our standard material over one year prior to the time of writing, because of ease of handling and its low porosity. The low porosity of this material has permitted more extensive bypass procedures with less loss of blood than with polyethylene.
However, recently two cases of false aneurysm formation
