• Height >190 cm/<160 cm (BTS).

• Previous idiopathic VTE.

• The last 4–6 weeks.

• Major surgery/trauma within.

• ≥2 risk factors under B.

flights are as follows:

General measures:

• All 30 min, isometric exercises.

• Cave: bending the popliteal veins.

• Do not take tranquilizers/sleeping pills:

• Cave: prolonged sleep in a cramped posture.

• Immobilization (e.g., plaster cast).

• Homozygous or combined congenital thrombophilia.

Recommendations for the prevention of deep leg vein thrombosis on long-haul

• Physical activity: regular walking around in the corridor every 2–3 h.

• Movement of the legs (calf muscles, e.g., "foot rocker") at the seat.

• Puerperium: within 2 weeks (BTS) orup to 6 weeks (BCSH) postpartum.

• Pregnancy.
