2) Tap the saphenofemoral junction
3) A transmitted impulse at the knee indicates an incompetence of the valves between the two hands

50
Q

What is the trendelenburg test?

A

1) Lie the patient flat and drain the superficial vein by raising the leg and stroking the vein towards the trunk
2) Apply pressure over the saphenofemoral junction, keep this pressure on as the patient stands
3) If the varicose veins don’t dilate on standing (you are preventing this by your hands acting like a valve) release your hands and you will see the veins refill as the patients saphenofemoral junction valve is incompetent

51
Q

What is the process of using a doppler for venous incompetence?

A

1) Hold the doppler probe over the saphenofemoral junction
2) Squeeze the calf muscle, in competent superficial veins you will hear a ‘whoosh’ as the blood flows upwards into the deep vein system
3) In a patient with an incompetent saphenofemoral hunction you will hear two waves as the blood flows upwards and then refluxes downwards again

52
