Review: elastic compression stockings prevent post-thrombotic syndrome in patients with deep venous thrombosis

Study selection and assessment: randomised controlled trials (RCTs) or controlled clinical trials that compared medical elastic stockings (pressure 20-30 mm Hg or 30-40 mm Hg at the ankle) and compression bandages with bed rest, no intervention, or placebo stockings. Secondary outcomes included complications and adverse effects (pulmonary embolism within 2 wk of treatment, discomfort, pain, swelling, pressure sores, and recurrence of thrombosis).
