At Greater Pittsburgh Vascular Associates, we offer prescription-strength gradient compression stockings. These stockings are worn on the legs from the foot to the upper thigh, or to just below the knee. This class of stocking creates pressure up the leg and is important in keeping blood from pooling and clotting. The stockings are indicated as an initial treatment for venous insufficiency and also must be worn for two weeks after any venous procedure. You need to be fitted by a specially trained member of our staff to be sure that the stocking fits appropriately.
