Very Late Stent Thrombosis in a Drug-Eluting Stent due to Interruption of Anti-Platelet Agents in Patients With Acute Myocardial Infarction and Thrombocytosis.

Stent thrombosis is a fatal complication in patients who have undergone percutaneous coronary intervention, and discontinuation of anti-platelet agent is a major risk factor of stent thrombosis. We report a rare case of very late stent thrombosis (VLST) following discontinuation of anti-platelet agents in a patient who experienced acute myocardial infarction and essential thrombocytosis. She had undergone implantation of a drug eluting stent (DES) and a bare metal stent (BMS) two and half years prior to her presentation. VLST developed in DES, not in BMS, following interruption of anti-platelet therapy.
