Patient with Recent Coronary Artery Stent Requiring Major Non Cardiac Surgery

Abstract

Anaesthesiologists are increasingly confronted with patients who had a recent coronary artery stent implanta-tion and are on dual anti-platelet medication. Non cardiac surgery and most invasive procedures increase the risk of stent thrombosis especially when procedure is performed early after stent implantation. Anaesthesiologist faces the dilemma of stopping the antiplatelet therapy before surgery to avoid bleeding versus perioperative stent thrombosis. Individualized approach should be adopted with following precautions. i) In a surgical patient with a history of percu-taneous coronary intervention (PCI) and coronary stent, determine the date of the procedure, the kind of the stent inserted and the possibility of complications during the procedure. ii) Consider all patents with a recent stent implan-tation (e.g. less than three months for bare metal stents and less than one year for brachytherapy or drug eluting stents as high risk and consult an interventional cardiologist. iii) Any decision to postpone surgery, continue, modify or discontinue antiplatelet regimes must involve the cardiologist, anaesthesiologist, surgeon, haematologist and the intensivist to balance the risk and benefit of each decision
