The company said VEST (Venous External SupporT) is a kink resistant cobalt-chromium external support applied on the outer surface of saphenous vein grafts when used in Coronary Artery Bypass Grafting (CABG) surgery.
Currently, nearly half of all saphenous vein grafts (a superficial leg vein used to bypass blocked coronary arteries) fail within 18 months because of inflammation and Intlmal hyperplasia, Inward growth of cells in the vessel's Inner lining that can block blood flow to the heart.
He has undergone coronary artery bypass graft operation with saphenous vein grafts placed to the left anterior descending coronary artery and the largest obtuse marginal branch of the left circumflex coronary artery.
Vascular conduit grafts are the only realistic option for insitu replacement of infected prosthetic grafts, and saphenous vein grafts are ideal for limb-salvage and during coronary artery bypass when autologous conduit is unavailable.
Angiography revealed that left internal thoracic artery (LITA) graft to left anterior descending artery (LAD) and saphenous vein grafts to posterior descending artery (PDA) branch of the right coronary artery (RCA) and second obtuse marginal (OM) branch of the circumflex artery (CX) correspondingly were patent.
