Ultrasonic doppler examination

Angiological examination method with the ultrasound Doppler for the diagnosis of chronic venous insufficiency and arterial occlusive disease. The examination method is particularly suitable for detecting insufficiency of the crust.

• In healthy veins, a flow surge at the end of the inspiratory period can be heard due to a discontinuous, breath-dependent flow in the veins. In the Valsalva test, no sound is audible when there are sufficient valves due to a flow stop.
• In case of pelvic vein thrombosis: higher frequency continuous flow noise.
• In case of muzzle valve insufficiency: cannon beat during the Valsalva test.
• Clear retrograde flow noise in the exspirium and in the Valsalva test can be detected via insufficient perforating veins. Similarly, truncal varicosis must be secured by a "Doppler" examination of the vena saphena magna.
