A Case of Emergency Off-Pump Coronary Artery Bypass Grafting after DES Stenting

Abstract

A 75-year-old man was admitted with symptoms of unstable angina pectoris. The patient was initially treated with ticlopidine and aspirin after first undergoing percutaneous coronary intervention (PCI) by means of a drug eluting stent (DES). Coronary angiography thereafter showed re-stenosis in left main trunk and two-vessel disease. As a result, emergency off-pump coronary artery bypass grafting (OPCAB) was therefore performed. However, major bleeding (3, 245ml) occurred after OPCAB. Therefore, a re-thoracotomy operation had to be performed to stop the bleeding. Based on the above findings it is important for surgeons to keep in mind that pre-operative ticlopidine administration can increase the risk of re-operation for hemostasis, while also potentially increasing and the requirements for blood and blood product transfusion both during and after OPCAB surgery.
