title: Effect of aprotinin (Trasylol) on aorta-coronary bypass graft patency.
abstract: To determine the effect on aorta-coronary bypass grafts of high-dose aprotinin, a drug known to be effective in reducing bleeding after all forms of heart operations, a prospective double-blind study was performed. Graft patency was assessed noninvasively 7 to 12 days (median 9 days) postoperatively in 90 patients. In the aprotinin group, 38 of 43 patients had all grafts patent compared with 43 of 47 in the placebo group. In each group, respectively, 126 of 131 grafts versus 134 of 138 grafts were patent. Neither difference was statistically significant (p > 0.05). Blood loss and homologous blood use were significantly reduced in the aprotinin-treated patients. In this study, high-dose aprotinin did not result in early saphenous vein graft occlusion after aorta-coronary bypass operations. This is further evidence that aprotinin reduces hemostatic derangement during cardiopulmonary bypass without creating a "prothrombotic" situation.
