Great saphenous vein valve function test

Great saphenous vein valve function test is used to evaluate the functional status of great saphenous vein valve. It is a common non-invasive examination method.

The great saphenous vein is the main connecting channel between deep and superficial venous system of human lower limbs. It is located inside the great saphenous vein and plays the role of preventing blood reflux. The great saphenous vein valve function test is performed with the help of professional doctors when the patient is in supine position. The functional status of valve can be better evaluated by observing the direction and speed of blood flow in the great saphenous vein. Under normal circumstances, blood flow in the great saphenous vein should flow upward, i.e. from the foot to the heart, during muscle contraction, and flow should stop or flow less reversely during muscle relaxation. It

should be noted that the great saphenous vein valve function test is an auxiliary test method, and the results need to be combined with clinical symptoms and other relevant test results.
