Comparison between saphenous vein and Dacron Velour grafts for femoropopliteal bypass
Insights
Saphenous vein grafts show superior long-term patency (90%) compared to Dacron Velour grafts (45%) for femoropopliteal bypass in arteriosclerotic occlusive disease.
Area of Science:
- Vascular Surgery
- Biomaterials Science
Background:
- Arteriosclerotic occlusive disease of the femoral artery necessitates bypass grafting.
- Femoropopliteal bypass is a common surgical intervention.
Purpose of the Study:
- To compare the long-term patency rates of saphenous vein grafts versus Dacron Velour grafts in femoropopliteal bypass.
- To evaluate the effectiveness of these grafts in preventing limb loss.
Main Methods:
- A retrospective analysis of 138 femoropopliteal grafts performed over five years.
- Comparison of 81 saphenous vein grafts with 57 Dacron Velour grafts.
- Assessment of graft patency at three years and limb salvage rates.
Main Results:
- Saphenous vein grafts demonstrated significantly higher patency at three years (90%) compared to Dacron Velour grafts (45%).
- Twenty-seven percent of patients presented with threatened limb loss, with amputation averted in all but 5%.
- Intraoperative flow measurement was not a reliable predictor of long-term graft patency.
Conclusions:
- Saphenous vein grafts are a more durable option for femoropopliteal bypass in arteriosclerotic occlusive disease.
- Effective limb salvage is achievable with current surgical techniques.
- Intraoperative flowmetry requires further investigation for its role in predicting graft success.
Abstract:
One hundred and thirty-eight femoropopliteal grafts were performed for arteriosclerotic occlusive disease of the femoral artery in a five-year period. One group of patients who had 81 saphenous vein grafts was compared with a similar group who had 57 Dacron Velour grafts. At three years 90% of the vein grafts were patent, compared to 45% of the Dacron Velour grafts. Twenty-seven per cent of all patients presented with threatenened limb loss. Amputation was averted in all but 5%. Intraoperative flow measurement did not prove to be a reliable indicator of long-term patency.
