Factors influencing 1-year patency of coronary artery saphenous vein grafts. Studio Indobufene nel Bypass Aortocoronarico (SINBA).

The study suggests that vessel diameter, wall motion of the vessel-dependent myocardial region, and location of the grafted vessel are the main determinants of SV coronary graft patency during the first postoperative year. Knowledge of these artery-specific factors may provide a basis for estimating the risk of graft occlusion, thereby modifying surgical strategy and postoperative surveillance.
