The phlebography (also ascending phlebography ) is a variant of venography , which is carried out mainly in suspected impaired venous valve function or varices. It is considered the reference method ("gold standard").
It is usually carried out using the method developed further by W. Hach in 1976.
execution
This examination is usually carried out in the same session as the venography. The patient is positioned on a tilting table at an angle of 45-60 degrees. Contrast agent is injected into the vein through an intravenous access on the back of the foot of the leg to be examined . So that the contrast agent does not flow into the superficial but into the deep veins to be examined, the superficial ones are blocked with an ankle congestion, i.e. tied off. In the subsequent x-rays, the leg veins are shown and examined for pathological changes. A thrombosis, for example, is characterized by a clearly delimited filling defect.
In press phlebography, the venous valve function is examined in particular. For this purpose, the patient is asked to perform a Valsalva maneuver (forceful exhalation with closed mouth and nose) or to tense the abdominal muscles. This pressing artificially increases the venous pressure for a short time. If the venous valve function or varices are disturbed, a pathological reflux can be shown radiologically.
