The horns of the dilemma, in the anaesthetic and surgical management of patients in the first 3-6 months after the 1st generation DES insertion, were between the risk of bleeding from continued clopidogrel treatment and the risk of instent thrombosis and myocardial infarction following discontinuation of dual antiplatelet therapy, clopidogrel and aspirin. Initial accounts of early catastrophic cardiac and haemorrhagic complications, at the time of elective or emergency surgery, following DES insertion, were followed by equally worrying reports of instent thrombosis many months after DES insertion. Initial recommendations for the conduct of safe operations were propagated in the literature before formal guidelines were produced. This article summarises the issues identified in the development of interventional cardiology particularly DES and the requirement for ongoing antiplatelet therapy.
