[Graduated and constant compression of the lower extremities in the prevention of postoperative deep venous thrombosis and of pulmonary thromboembolism. Clinical trial].

The authors report their experience with graded-pressure elastic hose (TED Stockings) for the prevention of deep venous thrombosis of the lower limbs and pulmonary embolism in high-risk, bedridden postoperative patients. The trial was designed according to a closed sequential program and gave positive, statistically significant results in terms of preventing pathology with this type of hose.
