The lesser saphenous vein: an underappreciated source of autogenous vein

Abstract

Use of the ipsilateral greater saphenous vein for arterial bypass procedures is frequently limited by previous stripping, bypass operations, or anatomic unsuitability. In such cases the contralateral greater saphenous vein or arm veins are often used. However, over the past 5 years we have used the lesser saphenous vein as a preferred alternative autogenous vein. Duplex scanning has been used in 311 cases for preoperative mapping and assessment with excellent correlation with actual anatomy found at operation. Harvest of the lesser saphenous vein has been facilitated by the use of a medial subfascial approach not requiring special positioning of the leg. A total of 91 lesser saphenous veins have been used for arterial bypass procedures; 66 of these were repeat cases. Vein use was 90.2%. In 40 of these cases the lesser saphenous vein was used as the entire conduit, including 10 in situ, 20 reversed vein (including 18 for coronary artery bypass), and 10 orthograde vein bypasses. In the remaining 33 cases the lesser saphenous vein was spliced to another vein to complete a bypass procedure. In the entire group, patency was 77% at 2 years. These data suggest that the lesser saphenous vein should be a principal alternative to ipsilateral greater saphenous vein for arterial bypass because of its ready availability, high use rate, ease of harvesting and preparation, and ideal handling characteristics.
