Brief summary

The purpose of this study was to investigate whether the no-touch saphenous vein grafts that were used in coronary artery bypass surgery between 2003-2008 had a patency rate comparable to the left internal thoracic artery when the vein grafts were anatomised to the left anterior descending artery.

Interventions

PROCEDURENo-touch harvesting technique

The saphenous vein is harvested with a pedicle of surrounding tissue.
