Optimizing Saphenous Vein Site Selection Using Intraoperative Venous Duplex Ultrasound Scanning

Greater saphenous vein evaluation from computed tomography angiography as a potential alternative to conventional ultrasonography

“…Although all vein bifurcations, varicosities, and stenoses were identified on CTA, only 20% of the patients had documented venous abnormalities, compared with the expected rate of 30% to 60%. [5][6][7] Therefore, it is inferred that documentation of venous abnormalities was not uniform in US evaluation and prevents comparison. However, in a review of factors affecting infrainguinal bypass failure in 1404 patients, Schanzer et al showed that bypass graft diameter, more than the presence of venous abnormalities, had the most significant influence on loss of patency at 1 year.…”

“…These variants are present in 30% to 60% of patients. [5][6][7] By identifying GSV diameter and relevant anatomic features, preoperative GSV evaluation may help avoid unnecessary dissection and decrease operative time. 8 Preoperative vein mapping decreases wound complications from 17% to 2%.…”

Endoscopic harvest of saphenous vein: a lesson learned from 1,348 cases

“…Ultrasound scanning provided benefits in detecting an abnormal vein course, identifying a suitable conduit in reoperative procedures, and precisely locating vein segments for endoscopic surgery. Optimizing incision-site selection eliminated blind exploration for vein conduit, improved conduit planning, and expedited surgical dissection during endoscopic vein harvest [16].…”

Simultaneous endoscopic radial artery and great saphenous vein harvesting for redo coronary artery bypass grafting. A report of two cases

“…Moreover, the clinical examination has its limitation in the conduit quality assessment. Further investigation should be carried out prior to harvesting in relation to gain high-quality conduits 8,9 . The great saphenous vein as well as the radial artery are easily accessible for ultrasound study.…”
