Abstract

The aim of this study was to compare duplex ultrasound (DU) and contrast venography (CV) for the detection of venous thrombosis, stenosis, and occlusion in the subclavian, innominate, and jugular veins and superior vena cava. Forty-seven patients had both studies over a 35-month period. A total of 57% were abnormal by CV. DU demonstrated a sensitivity of 81%, specificity of 90%, overall accuracy of 85%, positive predictive value of 91%, and negative predictive value of 78%. CV was more sensitive than DU for detecting partial thrombi in the midsubclavian, central left innominate, and superior vena cava, as well as segmental midsubclavian occlusion and was superior in differentiating central left innominate stenosis from thrombus. However, only one thrombus missed on DU was isolated and acute. DU was able to visualize segments not visualized on CV central to subclavian vein occlusion. DU detected seven instances of jugular vein abnormalities not visualized by CV. No isolated superior vena cava abnormalities were seen in this series.
