  • Title: Valvulotomy of valves in the saphenous vein graft before coronary artery bypass.
    Author: Mills NL, Ochsner JL.
    Journal: J Thorac Cardiovasc Surg; 1976 Jun; 71(6):878-9. PubMed ID: 1083926.
    Abstract:
    Occasionally, repeat angiograms disclose turbulence, with or without clot formation, at the valve sites in saphenous veins used as coronary artery bypass grafts. A simple valvulotomy may be used to split these valves to allow a more even flow and to avoid the valve recess where air may be trapped or thrombus formed. A potential cause for perioperative infarction or graft failure may thus be avoided.
