مسافر سيركب رحلة طيران طويلة ١٢ ساعة، ولديه تاريخ جلطة سابقة. أي نصيحة للوقاية من جلطة الساق؟

A traveller with previous DVT is taking a 12-hour flight. Which advice helps prevent a leg clot?

1. Sit without moving all flight to avoid dizziness
2. Walk, move the ankles, drink water, wear stockings
3. Take strong sleeping tablets for the whole long flight
4. Drink alcohol to relax and sleep most of the flight

Answer: B) Walk, move the ankles, drink water, wear stockings. Prolonged sitting causes venous stasis. Movement, ankle exercises, fluids and compression stockings reduce risk, and a doctor may advise anticoagulation for high risk. Alcohol and sedatives increase immobility and dehydration.
