Does real-time venous ultrasound accurately diagnose deep vein thrombosis?
Real-time venous ultrasound is a highly sensitive and specific non-invasive test for detecting femoral or popliteal deep vein thrombosis.

Supports real-time venous ultrasound for suspected femoral/popliteal DVT; leaves open need for prospective validation across settings.
Deep vein thrombosis (DVT) is a common clinical condition, which may cause pulmonary embolus in as many as 20% of those affected (Baxter, 1997). The evolution of real-time venous ultrasound in the 1980s provided a rapid, non-invasive and relatively cheap alternative test for DVT. Such techniques now have a reported sensitivity and specificity in detecting femoral or popliteal vein thrombus of >95% and >98% respectively. Other indications for venous ultrasound are included in Table 1.
