Pre-operative long saphenous vein mapping predicts vein anatomy and quality leading to improved post-operative leg morbidity.

Long saphenous vein harvesting for coronary bypass surgery is associated with significant morbidity. Furthermore, vein quality is often variable sometimes requiring incisions in both legs. This prospective randomised control study assessed the usefulness of pre-operative long saphenous vein mapping in terms of conduit quality and location, incision lengths and post-operative morbidity.
