Why the study?
Saphenous vein graft failure is predominantly seen at the valve site, and avoiding valves during harvest could help reduce graft failure.
Does upright CT improve the detection of saphenous vein valves and tributaries compared to supine CT in healthy volunteers and cadaver samples?

Upright CT may aid saphenous vein mapping for grafting; leaves open impact on bypass outcomes.
Does upright CT improve the detection of saphenous vein valves and tributaries compared to supine CT in healthy volunteers and cadaver samples?
Upright CT significantly improves the non-invasive detection of saphenous vein valves and tributaries compared to supine CT, which may aid in graft assessment for bypass surgery.
