Iron Deficiency Anemia as a Rare Risk Factor for Recurrent Pulmonary Embolism and Deep Vein Thrombosis

Iron deficiency is a well-known cause of anemia. However, it is an under-recognized cause of venous thromboembolism (VTE). Iron deficiency predisposes to VTE mainly by inducing thrombocytosis, which can lead to a hypercoagulable state. Identifying iron deficiency as a possible cause of thromboembolic phenomena has clinical significance since this is a potentially avoidable risk factor. This case report serves as a reminder that iron deficiency is an important risk factor for VTE that should be considered in the evaluation of patients. This is particularly true in patients like ours who have recurrent venous thromboembolic disease.
