An Unusual Case of Acute Stent Thrombosis: A Review of a Rare Cause of Acute Stent Occlusion

Abstract

We present the case of a 55 year old woman diagnosed with an ST-elevation myocardial infarction, on the background of receiving chemotherapy for metastatic ovarian cancer. She underwent primary angioplasty followed by a repeat angioplasty two hours later due to acute stent thrombosis. She was subsequently diagnosed to have acute severe thrombocytosis. This case highlights the role of exploring a broad differential diagnosis in cases of recurrent acute stent thrombosis, and presents a very rare case of reactive thrombocytosis in a patient on systemic anti-cancer treatment presenting as a myocardial infarction. It highlights the benefits of inter-specialty liaison for delivering better patient care especially in complicated treatment regimes for a number of disorders in various medical specialties. Case Presentation A 55 year old woman was admitted to the emergency department with acute onset severe chest pain and shortness of breath. Her other relevant history was metastatic ovarian cancer for which she was being treated with gemcitabine/carboplatin chemotherapy, and hormone therapy (letrozole) for breast cancer. She had no identifiable cardiovascular risk factors.
