Arm veins versus contralateral greater saphenous veins for lower extremity bypass reconstruction: preliminary data of a randomized study.

BACKGROUND: The aim of this randomized study was to determine whether arm vein (AV) or contralateral greater saphenous vein (CGSV) is the better alternative vein source for lower extremity bypass reconstruction. METHODS: Consecutive patients with absent ipsilateral greater saphenous vein undergoing lower extremity revascularization were allocated to group A (AV bypass) or B (CGSV bypass). RESULTS: From 6, 2010, to 11, 2013, 64 patients (32 each group) were randomized. In all, 29 of 93 patients had to be excluded for various reasons. Median age was 76 years vs. 71 years (P = 0.01) for group A and B patients. There were no statistically significant differences regarding gender, cardiovascular risk factors, redo bypass procedures (P = 0.77), below-knee bypass procedures (P = 0.61), median bypass length (P = 0.6), and median length of incision on ipsilateral leg to perform anastomoses (P = 0.2) between group A and B patients, respectively. Incisions for vein harvest were longer in group A (P = 0.003). Overall surgical site infections (SSIs, P = 1.0) and SSI from vein harvest (P = 1.0) were equally distributed. No patient was lost to follow-up (17 vs. 18 months, P = 0.74). There was no statistically significant difference regarding primary (P = 0.77) and secondary (P = 0.25) patency rates at 1 year (group A: 52% vs. group B: 54% and group A: 72% vs. group B: 61%) and at 2 years (52% vs. 48% and 64% vs. 61%), respectively. There were 4 vs. 6 major amputations (P = 0.23) and 5 vs. 2 deaths (P = 0.1) in groups A and B during follow-up. CONCLUSIONS: Preliminary results suggest that both AV and CGSV may serve as a secondary vein bypass graft equally well.
