Early Graft

To determine if specific antiplatelet therapy improved graft patency after coronary artery bypass grafting (CABG) -we compared (1) aspirin(325 mg qd), (2)aspirin(325 mg tid),(3) aspirin and dipyridamole(325 mg and 75 mg resp.tid), (4) sulfinpyrazone(267 mg tid) and (5) placebo(tid).Therapy was started 48 hours before CABGexcept for aspirin. When aspirin was a treatment,one 325 mg dose was given12 hours before surgery. Graft patency data were obtained early, one week, and then later, one year, after surgery. Preliminarydata, based on local interpretation of the angiograms at each center, in the firs 496 patients (1711 grafts), revealed thefollowing early graft patencies: aspiri qd (93%), aspirin tid (93%), aspirin and dipyridamole (93%),and sulfinpyrazone (92%). All these therapies improved(P<0.005)early graft patency compared to placebo (84%). Chest tube drainage measured within the first 35 hours after CABG revealed that the median loss with aspirintid (1114 ml) and aspirin and dipyridamole (972 ml) exceeded (P<0.001) placebo (802 ml) while aspirinqd (880 ml) and sulfinpyrazone (750 ml) did not. The reoperation rate was greater(P<0.01) in all the treatment groups thatcontained aspirin (6.1%) compared to the two non aspirin groups (1.9%). Overall operative mortality was 2.1%. In conclusion, graft patency was improved early after CABG with antiplatelet therapy. Two regimens which included preoperative aspirin has increased blood loss after CABG and preoperative aspirin increased the reoperation rate.

Early Graft

The most common causes of myocardial ischemia and myocardial infarction early after coronary artery bypass grafting surgery are early graft occlusion/thrombosis or occlusion/ thrombosis of coronary arteries due to advanced coronary heart disease. We describe a case of postoperative myocardial ischemia due to an uncommon and quickly reversible cause: mechanical compression of a vein graft by a 19F flexible silicone mediastinal drainage tube.

Transit Time Flowmetry

Intraoperative Transit Time Flowmetry is currently recommended to assess graft patency during coronary artery bypass grafting (CABG), especially in presence of haemodynamic instability or inability to wean the patient from cardiopulmonary bypass, new regional wall motion abnormalities, or significant ventricular arrhythmias. The VeriQ™ system is one of the currently available systems, which detects imperfections that may be corrected by graft revision. In this case report, multivessel coronary spasm (CS) post-CABG interferes with these intraoperative parameters misleading initially into false results. Cardiac surgeons should bear in mind the limit of VeriQ in distinguishing between graft failure and CS. Angiography may be considered in patients with decreased graft flow despite revision of anastomosis and vasodilatory treatment for the definitive diagnosis.
