DVT may occur in ambulatory patients presenting to the emergency department (ED) with leg pain and/or swelling, and is also a frequent complication of critical illness due to multiple and often coexisting risk factors, including immobility, surgery, trauma, indwelling devices, malignancy, and inflammatory states. A vexing problem is the unreliability of the symptoms and signs of DVT in the critical care setting, which are often limited by obesity, edema, and surgical dressings. In the intensive care unit (ICU), 10%–100% of DVTs are clinically unsuspected, and pulmonary embolism is the most frequent incidental autopsy finding, directly contributing to death in approximately 5% of all cases.
