Evidence‑Based Recommendations for Compression Stocking Wear

Air Travel (VTE Prophylaxis)

The Chest guidelines advise that patients should apply compression stockings 2–3 hours before boarding and keep them on for the entire flight, using ankle pressures of 20–30 mmHg to reduce venous stasis during travel. 1
Proper fit is critical for travel use: over‑tight stockings around the knee can impede venous return and may increase the risk of deep‑vein thrombosis, whereas overly loose stockings fail to provide adequate compression. 1

The American Heart Association recommends daily wear of compression stockings for up to 2 years after a diagnosed deep‑vein thrombosis; however, evidence from comparative studies suggests that 1 year of use may achieve similar efficacy. 2
In a 2‑year follow‑up, 56 % of patients reported frequent use (≥ 3 days per week), although the SOX trial later questioned the overall benefit of stockings for PTS prevention. 2
Clinical follow‑up at 3 months should assess actual wearing time and, if needed, adjust compression strength or patient expectations to maintain therapeutic benefit. 2
Compression stockings should not be prescribed to patients with peripheral arterial disease, as they can worsen arterial inflow limitation. 2

Graduated compression stockings are not recommended for patients with acute stroke because they increase the risk of skin damage without providing DVT prophylaxis, as highlighted by the Annals of Internal Medicine and International Journal of Stroke. [5][6]3

For patients with severe post‑thrombotic syndrome and marked edema, intermittent pneumatic compression devices should be used several hours each day, demonstrating significant edema reduction in clinical studies. 7
