Preservation for Future use of the Autologous Saphenous Vein during femoro-popliteal Bypass Surgery is Inexpedient

DESIGN: Post-hoc analysis of data acquired in a randomized multi-centre clinical trial comparing two different vascular prostheses (ClinicalTrials.gov ID: NCT 00523263). PATIENTS AND METHODS: The true frequency of ipsilateral saphenous vein use in subsequent femoro-popliteal and coronary bypass surgery was investigated through case-record analysis with a median follow-up of 60 months in 100 consecutive patients, that received a prosthetic femoro-popliteal bypass between 1996 and 2001. RESULTS: An ipsilateral secondary femoro-popliteal bypass was performed in 11 patients (11%) at a mean interval of 34 months (range 1-96). The ipsilateral saphenous vein was applied for these procedures in 8 cases (8%). The cumulative probability of receiving a subsequent bypass was 8% at 3 years and 10% at 5 years follow-up respectively. One patient (1%) underwent CABG at 8 years follow-up with the use of ipsilateral lower leg saphenous vein segments only. CONCLUSION: Preservation of the greater saphenous vein in supragenicular femoro-popliteal bypass surgery is not a valid argument for application of prosthetic material.
