Perthes' test

Related people

A clinical test for assessing the patency of the deep femoral veins, used in preparations for operation for varicose veins. With the patient standing and veins filled, a tourniquet is placed around the mid-thigh and the patient walks for 5 minutes. If the saphenous veins collapse below the tourniquet the deep veins are patent and the communicating veins are competent; if unchanged, both saphenous and communicating veins are incompetent and if the veins increase in prominence and pain occurs the deep veins are occluded.
