    REDUCING OVERDISTENSION

    As part of your routine, you likely check the harvested vessel for leaks by manually flushing it with a standard syringe prior to grafting. However, the amount of pressure exerted on the endothelial lining of the vessel wall is not easily controlled or measured, and could result in internal pressures of up to 600 mm Hg, causing overdistension and inadvertently damaging the endothelial layer. Damage to the endothelium may increase the likelihood of graft failure.7,8,9
