[In situ venous bypass in femoro-tibial arterial reconstruction]
Insights
Surgery using the in situ great saphenous vein for femoro-tibial arterial bypass is effective for patients with limb-threatening ischemia. This surgical technique offers a viable option for critical limb ischemia patients.
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
- Surgical Innovation
Context:
- Peripheral artery disease often leads to critical limb ischemia, characterized by rest pain or tissue loss.
- Surgical revascularization is crucial for limb salvage in patients with severe peripheral artery disease.
- The great saphenous vein is a common autograft for arterial bypass procedures.
Purpose:
- To evaluate the efficacy and outcomes of using the great saphenous vein in situ for femoro-tibial arterial bypass in patients with critical limb ischemia.
- To assess the patency rates and patient survival following this specific surgical intervention.
- To determine if the in situ great saphenous vein bypass is a suitable technique for limb salvage.
Summary:
- This study reports on 26 patients undergoing in situ great saphenous vein femoro-tibial arterial bypass for limb salvage.
- Vein valves were destroyed using an intraluminal valve cutter. The mean follow-up was 24 months.
- Three bypasses occluded; seven patients died from cardiac causes. The study supports surgical intervention for rest pain or gangrene.
Impact:
- The in situ great saphenous vein bypass demonstrates potential as a preferred technique for treating critical limb ischemia.
- This approach may encourage surgeons to consider revascularization for patients with severe peripheral artery disease and rest pain.
- Further research can optimize this technique to improve long-term patency and reduce bypass occlusion.
Abstract:
We present the results of 26 consecutive patients operated because of rest pain or threatened loss of limb. The great saphenous vein was used in situ as femoro-tibial arterial bypass. Destruction of the vein valves was performed using an intraluminal valve cutter mounted on a fogarty catheter. Three bypasses occluded during the observation period which lasted for 24 +/- seven months (mean +/- standard deviation). Seven patients died from heart disease. Our results indicate that one should not hesitate to perform surgery on patients with rest pain or gangrene. The in situ method used in the present study seems to be the technique of choice in treating these patients.
