Choice of Material for Above-Knee Femoro-Popliteal Bypass Prosthetic Graft (PopUp)

Choice of Material for Above-Knee Femoro-Popliteal Bypass Prosthetic Graft. Multicenter Randomized Study of an Impregnated Knitted Polyester Prosthesis Vs. PTFE (Uni-Graft Vs Gore-Tex).

This trial was designed to challenge the wide held view that polytetrafluoroethylene (PTFE) performs better than Dacron for above knee femoropopliteal bypass.

Objective: To investigate whether patency rates of 6 mm gelatine coated, knitted, double velour polyester prostheses are equal to the 6 mm thinwalled ePTFE prostheses as above-knee femoro-popliteal bypass graft

Inclusion Criteria:

• All patients who require revascularisation of the lower extremity suitable for above-knee femoro-popliteal bypass surgery.

Exclusion Criteria:

• pregnancy
• No consent to participate in the study
• Previous enrollment in the study
• follow-up is not possible
