Summary
In contrast to the arteries, spontaneous flow in the leg veins is not sufficient for
good diagnosis. Therefore, provocation manoeuvres are used to induce blood flow. Breathing
and the Valsalva manoeuvre are classically used. Over the past few years, dynamic
manoeuvres and manoeuvres closer to physiological conditions have been developed,
such as the Paraná manoeuvre, in which the patient is pushed slightly forward in order
to activate the gastrocnemius muscles, the Wunstorf manoeuvre, in which the forefoot
is raised, or the orthostatic manoeuvre, in which the patient is placed in the supine
position and then raised upright again in order to test the closure of the valves.
All of these procedures are presented and compared with each other.
