[Dynamic contrast medium-aided ultrasound cavography in patients with a caval filter].
In 35 patients during 42 examinations, vena-caval blood flow was visualized by application of a new ultrasonic contrast medium (Echovist) via a dorsopedal vein. A caval filter had previously been implanted in 32 patients. In 94 out of 99 cases, application of the contrast medium allowed a diagnostically relevant enhancement of the echogenicity of the caval blood flow. In addition, the caval filters allowed altered flow geometry to be depicted in detail.
