Improved Preservation of Saphenous Vein Grafts by the Use of Glyceryl Trinitrate–Verapamil Solution During Harvesting

Abstract

First, pharmacological treatment of SV during harvesting, especially with GV solution, allows the use of a lower distension pressure and reduces the breakdown of high-energy phosphates in the vein wall. Second, topical and intraluminal use of GV solution during vein harvesting improves endothelial coverage compared with the topical use of Pap or no pharmacological treatment.
