Summary
For femoro-popliteal bypass grafts below the knee, polytetrafluoroethylene (PTFE) grafts offer comparable patency to saphenous vein grafts. Preserving saphenous veins for coronary artery bypass is a key consideration for this choice.
Area of Science:
- Vascular Surgery
- Cardiovascular Research
Background:
- Femoro-popliteal bypass grafts are increasingly placed below the knee.
- Reversed saphenous vein is traditionally considered the optimal graft material.
Purpose of the Study:
- To evaluate alternative graft materials for below-knee femoro-popliteal bypass.
- To consider the implications of saphenous vein preservation for coronary artery bypass surgery.
Main Methods:
- Comparative analysis of graft patency rates.
- Review of surgical considerations for graft selection.
Main Results:
- Polytetrafluoroethylene (PTFE) grafts demonstrate comparable long-term patency to autologous vein grafts in this location.
- Saphenous vein harvesting adds surgical trauma and risks, and may be needed for coronary artery bypass.
Conclusions:
- PTFE grafts are a viable alternative for below-knee femoro-popliteal bypass, offering similar patency to vein grafts.
- Preserving saphenous veins for potential coronary artery bypass is an important factor in graft choice.
