Young woman with repeated late stent thrombosis: a case report

A 34-year-old woman with hypertension, obesity, and history of smoking presented with unstable angina and severe stenosis of the proximal left anterior descending artery. Percutaneous coronary intervention was performed with stent implantation resulting in adequate expansion. She was treated with aspirin and ticlopidine for 1 month, then only aspirin for 1 month. One year after stenting, she presented with acute myocardial infarction and total occlusion at the stent. Balloon angioplasty was performed. She took ticlopidine and aspirin for 9 months. Two months later, she presented with acute myocardial infarction with reocclusion at the stent. Blood examination showed no manifest collagen disease or thrombophilia. This case of repeated late stent thrombosis occurred in a young woman not treated by brachytherapy.
