Trendelenburg test

Tren·de·len·burg test

(tren'dĕ-lĕn-bĕrg),
a test of the valves of the leg veins; the leg is raised above the level of the heart until the veins are empty and is then rapidly lowered; in varicosity and incompetence of the valves the veins will at once become distended, but placement of a tourniquet around the leg will prevent distention of veins below the incompetent perforators or valves below the tourniquet.

Trendelenburg test

Etymology: Friedrich Trendelenburg
a simple test for incompetent valves in a person who has varicose veins. The person lies down and elevates the leg to empty the vein, then stands, and the vein is observed as it fills. If the valves are incompetent, the vein fills from above. If the valves are normal, they do not allow backflow of blood, and the vein fills from below.
