Risk calculators and risk factors for Deep vein thrombosis screening |
Value of screening
In-spite of identifying patients at increased risk of venous thromboembolism (VTE), there is no clear clinical value for screening the general population because:
- The strongest risk factor for VTE recurrence is a prior VTE event itself.
- VTE patients with unknown cause have a high rate of recurrence, after discontinuation of warfarin, irrespective of the presence of inherited thrombophilia.
- Anticoagulant prophylaxis is rarely recommended in asymptomatic affected family members, outside of high risk situations.
Screening methods
The sensitivity and specificity of compression ultrasound(CUS) for proximal deep vein thrombosis(DVT) are high (97 percent and 98 percent, respectively) [1] and the necessity for treating proximal DVT with anticoagulants is widely accepted [2]. On the other hand, the sensitivity and specificity of CUS for distal DVTs are lower [1] [3], and a meta-analysis by reported sensitivity of 50 percent to 75 percent and specificity of 90 percent to 95 percent [1].
Duplex ultrasound screening is typically used for DVT in asymptomatic trauma patients, but practice patterns vary in the United States [4].
Who should be screened?
Screening for inherited thrombophilia in patients who have DVT is discussed here.
