Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics, and obligatory medical device diagnostics – for differential diagnostic clarification.
- Compression phlebosonography (KUS, synonym: vein compression sonography); sonography (ultrasound examination) to document and check the compressibility of the deep veins in the legs and arms) – for suspected deep vein thrombosis (DVT); very safe procedure, especially in the case of thrombi (“blood clots”) of the femoral veins or popliteal vein [gold standard].
- Color-coded duplex sonography – in cases of suspected thrombi in the vena cava/pelvic veins.
- Venography (phlebography; radiographic imaging of the veins) – indicated (indicated) for sonographically unclear findings.
- Angiography (imaging of blood vessels by contrast medium in an X-ray examination) – when peripheral arterial occlusive disease (pAVK) is suspected.
