Risk Factors for Pulmonary Embolism

Remember that as many as 20-25% of patients with proven VTE (DVT and PE) will not have identifiable risk factors at the the time you evaluate them.
6 hours of flight (or car ride) with the knees flexed at about 90 degrees is considered by many to be a risk factor.
Inflammatory bowel disease (Crohns and Ulcerative Colitis) are hypercoagulable disorders and have been linked to VTE.
