Diagnostic advantages of vector flow (V-Flow) in venous system
What is it about?
With the help of the vector flow (v-flow) the direction and speed of the blood flow in the arterial and venous system can be represented very well by means of colour-coded vectors. If turbulence occurs in the context of stenoses or insufficiencies, undirected, long, red-coded vectors can be derived. A reflux occurring as a result of this can thus be made clearly visible. We showed this using the example of a valve insufficiency at the junction where the great saphenous vein meets the femoral vein, the so-called crosses.
Why is it important?
Insufficiency in the area of the crosses is caused by varicosis, which affects many older people in particular. The consequences can include deep vein thrombosis, open legs and eczema. With the help of the vector flow, this insufficiency and the associated reflux can be made very clearly visible and the function of the valves can be assessed. But not only in the venous system but also in the arterial system a visualisation of turbulences within the vessels can be of use.
