[The value of Duplex sonography in the diagnosis of deep leg and pelvic vein thrombosis].Bildgebung. 1987-1989; 56(2):52-6.B
50 cases, in which phlebography was indicated by clinical symptoms of deep venous thrombosis, were examined by duplex-sonography. In comparison with the phlebographic findings, duplex-sonography was 100% sensitive in detecting thrombosis of the popliteal, femoral and iliac veins and 89% respectively 95% and 100% specific. A sonographic performance of the calf veins was only possible in 44%, the sensitivity in these cases was 92%, specificity 50%. Thus, the non-invasive duplex-sonography is a very appropriate method to diagnose thrombosis of the popliteal region and proximal. For proving or excluding thrombosis of the calf veins phlebography remains necessary.
