Deep Venous Thrombosis T2 Critical Care Emergency Medicine YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-162824-2 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=55813683 RD 2024/04/25 AB In the United States, it is estimated that roughly 100 per 100,000 people per year experience a first-time venous thromboembolism (VTE). Of these cases, two thirds are caused by deep venous 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
