Trendelenburg's test I
Test for varicose veins. Patient lies on his back and raises his leg to empty the veins. A tourniquet is applied just below the saphenous opening. The patient is then stood up and the tourniquet removed in 60 seconds. Normally the vein should fill from below within 35 seconds with the tourniquet in situ. Earlier filling indicates incompetence of a communicating vein. If on release the veins fill rapidly from above it is due to incompetent sapheno-femoral valves.
