RESUMO
Antiplatelet therapy has been demonstrated to reduce the risk of cardiac events in patients presenting with acute coronary syndrome, yet all effective therapies also increase the risk of bleeding. This study aimed to test the hypothesis that patients undergoing coronary artery bypass grafting, who received clopidogrel within 5 days before surgery, have worse bleeding outcomes and blood transfusion requirements than those who stopped clopidogrel >5 days earlier. We recruited 342 patients who underwent on-pump elective coronary artery bypass grafting between January 2004 and December 2008. Of these, 191 stopped taking clopidogrel >5 days earlier, and 151 stopped ≤5 days before surgery. Postoperative drainage after 8 and 12 h and the total drainage were similar in both groups. There was no significant difference in the amount of blood products used. There was no reexploration in either group. It was concluded that preoperative clopidogrel exposure does not increase the risk of hemostatic reoperation or the requirements for blood and blood product transfusion during and after coronary artery bypass grafting.

A 6-year-old girl, a known case of Kawasaki disease, presented with acute thrombotic occlusion of right coronary artery (RCA) with symptoms of acute angina and myocardial dysfunction. She underwent beating heart off-pump coronary artery bypass graft (CABG) surgery with right internal mammary artery (RIMA) grafted to distal RCA. Follow-up computed tomography angiogram revealed well-flowing RIMA with no obstruction or kink. This case highlights the importance of CABG as a safe and life-saving procedure in expert hands, even for children in emergent conditions.
