MAQUET is starting a trial of its VASOSHIELD Pressure Controlling Syringe, a device the company wants every cardiac surgeon to use to flush harvested saphenous veins to check for leaks before coronary artery bypass grafting. A traditional syringe is typically used, which does not control the pressure of the liquid, often leading to tears within the intimal layer of the vessel. The VASOSHIELD has three settings (150, 250, or 350 mm Hg) that specify the maximum pressure that will be applied.
The study will enroll 30 patients undergoing elective CABG surgery who require at least two saphenous vein bypass grafts. Obtained using endoscopic vessel harvesting (EVH) techniques, each graft will be randomly assigned to receive vessel distension by either the MAQUET VASOSHIELD device or a standard syringe. The study endpoints include histological evaluation of vein grafts, assessment of endothelial function and measurement of nitric oxide synthase (NOS) activity, and endothelium-dependent relaxation and contraction.
