The most common presentations of venous thromboembolism (VTE) are deep vein thrombosis (DVT) of the lower extremity and pulmonary embolism. A risk factor for VTE, either hereditary or acquired, can now be identified in approximately 80 percent of patients. Furthermore, there is often more than one factor at play in a given patient. As an example, 50 percent of thrombotic events in patients with inherited thrombophilia are associated with an acquired risk factor (eg, surgery, pregnancy, oral contraceptives). In addition, some patients have more than one form of inherited thrombophilia and appear to be at greater risk for thrombosis.

The approach to the adult patient with deep venous thrombosis will be discussed here with an emphasis upon the use of diagnostic tests to establish an accurate diagnosis and the initiation of anticoagulant therapy. Indications for testing for an inherited cause of thrombophilia are addressed along with the potential implications of the discovery of an underlying thrombophilic defect for the patient and affected relatives.

NUMBER OF CREDIT HOURS: The Harvard Medical School designates this enduring material for a maximum of 1 AMA PRA Category 1 Credit™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

This course should take approximately 1 hours to complete.

COST: $20.00 for the average learner. Participants living in emerging nations receive a 50% discount or can register for free. See our International Pricing Page for details.

OVERALL LEARNING OBJECTIVES:

1. To improve acumen in diagnosing deep venous thrombosis
2. To update knowledge on parenteral and oral anticoagulant therapy
3. To impart new information related to genetic prothrombotic risk factors

CLINICAL LEARNING OBJECTIVES:

1. To review the epidemiology of venous thrombosis
2. To appropriately diagnose acute deep venous thrombosis and initiate appropriate anticoagulant therapy
3. To identify patients with thrombosis who should undergo testing for inherited hypercoagulability and quantify the risk of thrombosis in patients with hereditary prethrombotic states
4. To discuss criteria for life-long anticoagulation

METHOD OF PARTICIPATION:

Registrants participate in the learning process by answering interactive multiple choice questions that are dispersed throughout the case presentation. You must answer a question correctly in order to continue through the course. If you answer a question incorrectly, you will be prompted to try again.

In order to earn credit, physicians must complete the entire educational activity before the termination date (see above). Non-physicians may register for the course but are not eligible for AMA PRA Category 1 Credits™. Instead, non-physicians will earn a certificate of participation after successfully completing the course before its termination date.

COMBINATION OF MEDIA USED:

This internet enduring material is a case-based, interactive presentation comprised mainly of text, interactive questions, and images. A variety of media, including video clips, audio clips, and Flash animation, may be presented. Links to any necessary plugins are provided when necessary, but no plugins are required for general use of the CME website, and you may skip the multimedia presentation(s) within the course if you choose.

SAMUEL Z. GOLDHABER, MD Reviewer

Samuel Z. Goldhaber, MD, Professor of Medicine at Harvard Medical School, chairs the Venous Disease Coalition. Dr. Goldhaber is a Senior Staff Member of the Cardiovascular Medicine Division of Brigham and Women’s Hospital (BWH). He is Director of the BWH Venous Thromboembolism Research Group and serves as Principal Investigator of a broad range of randomized clinical trials and observational studies related to the prevention, treatment, and epidemiology of venous thromboembolism. Dr. Goldhaber is also Director of the BWH Anticoagulation Service, which cares for more than 2,000 patients. The March 10, 2005, New England Journal of Medicine published his large clinical trial that described a new method using electronic alerts to enhance venous thromboembolism prophylaxis. This intervention reduced symptomatic DVT and PE by 41%, without an increase in bleeding complications. Dr. Goldhaber is also the Principal Investigator of an ongoing multicenter trial on Physician Alerts for patients at high risk of DVT or PE who are not receiving prophylaxis. In May 2006, he co-chaired the 2-day Surgeon General’s Workshop on DVT, which was cosponsored by the National Heart Lung and Blood Institute (NHLBI). He also serves on the National Comprehensive Cancer Network and National Quality Forum to formulate new treatment and prevention guidelines for venous thromboembolism. He is President and one of four Founding Directors of the nonprofit North American Thrombosis Forum (www.NATFonline.org), one of the 19 organizations comprising the Venous Disease Coalition.
