Of these cases, two-thirds are caused by deep vein thrombosis (DVT).1 Much literature has been devoted to the occurrence of VTE in hospitalized patients who are ill or recovering from a surgical procedure. However, many patients present as outpatients to the emergency room with symptoms related to their VTE. This chapter focuses on the current practices for evaluation and diagnosis of DVT and hopes to help guide the emergency physician through the current evidence-based clinical practice guidelines for antithrombotic and thrombolytic therapy.2,3
