Prospective study demonstrates high diagnostic sensitivity of color Doppler imaging for deep vein thrombosis, indicating ultrasound should precede invasive phlebography.
The objective of this prospective study was to evaluate the accuracy of color Doppler imaging in comparison to phlebography in diagnosing phlebothrombosis. Five hundred and twenty-six phlebographies (reference method) were compared with 526 color Doppler sonographic examinations. Thrombosis diagnosed with color Doppler imaging showed a sensitivity of 98.0% (400 of 408). In 91.6% (482 of 526) of all examinations the extent of the thrombosis diagnosed with phlebography could also be seen with color Doppler imaging. When the clinical situation is unclear, color Doppler imaging should precede phlebography. Only when findings with ultrasonography are questionable should phlebography definitely be considered.
