PRIMARY PERCUTANEOUS INTERVENTION (PCI) IN A SAPHENOUS VEIN GRAFT
Abstract
Occlusion and degeneration of saphenous
vein grafts (SVGs) poses significant problems in
patients who have undergone coronary artery
bypass graft (CABG) surgery. In the first year
post-CABG SVG occlusion rate is
approximately 15%. SVG 10-year patency is
only 60%1-3. SVG failure is associated with a
significant increase in major adverse
cardiovascular events (MACE), including death,
myocardial infarction (MI), and the need for
repeat revascularization4. Factors predicting
venous graft occlusion include hypertension,
dyslipidemia, use of tobacco, and small target
vessel (diameter <2 mm)5.
