6.1
When it considered endoscopic saphenous vein harvest for coronary artery bypass grafting in 2010 (see section 7), the Committee had concerns about safety in the short and medium term. These concerns were related to the possible reduction in patency rates of endoscopically harvested vein grafts, with increased risks of re-intervention, myocardial infarction and death compared against open harvesting techniques. Evidence published since that time included large numbers of patients, and the Committee judged that it did not show increased occlusion rates or incidences of re-intervention, myocardial infarction or death for endoscopically harvested grafts.
