Postoperative Bare-Metal Stent Thrombosis 37 Days after Percutaneous Coronary Intervention: A Case Report

Perioperative coronary stent thrombosis is a life-threatening complication for patients undergo noncardiac surgery early after stent implantation. We present a case of fatal stent thrombosis immediately after revision total knee replacement (TKR)in 71-year-old woman, who underwent multiple bare-metal stents (BMSs) implantation 37 days before surgery. She had previously undergone emergency surgery due to septic knee arthritis before BMS implantation. Dual-antiplatelet therapy with aspirin and clopidogrel were administered four week, and then aspirin alone was continued until the day of surgery. However, within 1 hour after revision TKR, total stent occlusion of the left anterior descending artery and near total thrombotic occlusion of obtuse marginal artery oswere developed due to the antiplatelet drug resistance, which is one of the strongly suspected predictor. Unfortunately she was died despite of the successful coronary blood flow recoveries.
