Sigvaris anti-embolism thigh highs help prevent a deep vein thrombosis (DVT or blood clot) during bed rest and after surgery. These stockings provide 18-23 mmHg of graduated compression to reduce leg discomfort, swelling and to prevent blood clots. The Sigvaris Thigh Highs feature an open toe style, anatomical foot design and wide top band to keep the stockings comfortably in place. These stockings are made latex free to prevent allergic reactions. Great for patients transitioning from hospital to home care.
