Essential Thrombocytosis-Associated Thromboembolism in the Abdominal Aorta

Abstract

Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus and developed acute limb ischemia. The patient underwent aortic replacement successfully. The patient’s platelet count was controlled with hydroxyurea, and no recurrence was noted over 2 years of follow-up.
