Perthes Test

Perthes Test (pronounced: per-thiz test) is a clinical examination procedure used to assess the competency of the deep venous system of the lower extremities, particularly in the diagnosis of Deep Vein Thrombosis (DVT).

Etymology

The test is named after Georg Clemens Perthes, a German surgeon who first described the procedure in 1908.

Procedure

The Perthes test is performed with the patient in a standing position. A tourniquet is applied to the upper thigh to occlude the superficial veins but not the deep veins. The patient is then asked to walk around. If the veins of the calf do not become distended, it suggests that the deep veins are patent and the test is considered positive. If the veins become distended, it suggests that the deep veins are occluded and the test is considered negative.
