Obligatory medical device diagnostics.
- Duplex sonography (ultrasound examination: combination of a sonographic cross-sectional image (B-scan) and the Doppler sonography method; medical imaging technique that can dynamically visualize fluid flows (especially blood flow)).
- Color duplex sonography (vascular ultrasound) – ultrasound examination of the vessels (arteries, veins), with which the direction of blood flow in relation to the transducer is displayed in red or blue; this allows blood flow in arteries to be distinguished from that in the veins; the procedure allows statements about the presence and extent of circulatory disorders
Optional medical device diagnostics – depending on the results of the medical history, physical examination, laboratory diagnostics and mandatory medical device diagnostics – for differential diagnostic clarification.
- Ascending press phlebography (X-ray examination of the veins with contrast medium)* – before surgical therapy [gold standard].
* The examination takes place on an inclined X-ray table. On the dorsum of the foot, a fine cannula is inserted into a vein through which the X-ray contrast medium is injected. The superficial veins are tied off above the ankle to allow the contrast medium to drain through the deep leg veins. X-rays of the lower leg and knee veins are then taken from different levels to show the drainage of the contrast medium.
