Very late drug-eluting stent thrombosis in the perioperative period of endoscopic choledocholithotomy.

Very late stent thrombosis is an uncommon but life-threatening complication after drug-eluting stent implantation in patients with coronary artery disease. Discontinuation of antiplatelet therapy is reported to be the most powerful predictor of stent thrombosis. This article reports on a case of very late stent thrombosis 54 months after implantation of a drug-eluting stent, in a patient who discontinued dual antiplatelet therapy only 11 days before endoscopic choledocholithotomy, and argues in favour of continuing aspirin therapy perioperatively in surgical patients with low bleeding risk, even if dual antiplatelet therapy has been followed more than 12 months after stent implantation.
