The Perthes test on varicose veins. The leg receives an elastic bandage and the patient walks a few steps, we observe that the veins disappear. This is because the flow leakage from a deep-superficial connection in the thigh (non-physiological sense) was closed with the bandage and the blood was re-entered by a superficial-deep connection in the leg (physiological sense) where the P was drawn. We use the test to predict the cosmetic effect of CHIVA.
In the photos we have patient before and after the elastic band.
