January 15, 2015 updated by: Ninos Samano M.D., Örebro County Council

The Long-term Results of Coronary Artery Bypass Surgery When the No-touch Vein Graft is Anastomised to the Left Anterior Descending Artery.

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.
