However, the complete mapping of the venous system is necessary in order to select the most appropriate treatment. This is possible only with the assistance of special imaging examinations.
One of the most valuable imaging examinations is the Color Flow Duplex scan - also known as Triplex Scan.
This ultrasonic examination is entirely painless and completely tolerable for the patient. It can reveal the venous system, both the deep and the superficial, in particular detail. Apart from the imaging of the venous system, the Color Flow Duplex (Triplex) scan is able to reflect the presence of blood flow in the veins, as well as the direction of this flow.
It is important to determine the direction of blood flow because it is useful in the examination of the function of the veins, and especially of the valves. When the valves function properly, the direction of blood flow is always from the periphery to the heart. But when they are insufficient, blood reflux is observed during the examination. In this way, the Color Flow Duplex (Triplex) scan can indicate the spots where the valves are insufficient and there is blood reflux.
The test is performed at the clinic to all patients who are likely to suffer from venous insufficiency and lasts 15 to 30 minutes.
There are also other imaging examinations that may be necessary, depending on the case. Magnetic Resonance Venography is such a test, which is highly sensitive and specially used for the detection of venous insufficiency. It is performed by injecting a contrast agent and then by special processing of the images on a computer. It is available in several medical centers and it only necessary in the rare cases when the ultrasound scan cannot be diagnostic.
