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.
