Review of 210 autogenous vein by-pass operations

Area of Science:

• Vascular Surgery
• Arterial Disease Management
• Limb Salvage Procedures

Background:

• Femoro-popliteal arterial disease often necessitates surgical intervention.
• Limb salvage is a critical goal in managing peripheral arterial disease.
• Autogenous vein bypass is a common revascularization technique.

Purpose of the Study:

• To evaluate the long-term efficacy of autogenous vein bypass for limb salvage.
• To assess factors influencing graft patency in femoro-popliteal bypass.
• To determine the value of early re-operation for graft failure.

Main Methods:

• Retrospective review of 210 autogenous vein bypass operations.
• Life table method used to analyze patency rates.
• Analysis of factors including distal anastomosis, graft run-off, and lumbar sympathectomy.

Main Results:

• 57% five-year cumulative patency rate reported for autogenous vein bypass.
• Good graft run-off significantly correlated with better long-term patency (p = .036).
• Early re-operation (within 48 hours) for graft failure yielded a 59.9% five-year patency rate.

Conclusions:

• Autogenous vein bypass is a worthwhile procedure for limb salvage in femoro-popliteal arterial disease.
• Graft run-off is a key predictor of bypass success.
• Early re-operation for graft failure is a beneficial strategy to improve outcomes.
