flying and thromboembolism
-
incidence increases with flight duration, oestrogen use, PH DVT/PE, and co-existing predisposing conditions.
clinically evident episodes occur at an incidence of 1 per 4500 long-haul flights.
there is no evidence that risk is reduced by aspirin.
risk may be reduced by:
regular walks around the cabin - but not possible when sleeping and thus there is still risk
vigorous ankle flexion against resistance
lower leg compressive stockings
avoiding oestrogen Rx including OCP 2-3 months prior to travel
adequate fluid intake (avoid diuretics including alcohol and caffeine)
LMW heparin given immediately before the flight at the usual prophylactic dose
1), or
warfarin but given the risk of bleeding, these are only recommended for those at high risk of DVT/PE.
moderate DVT risk
relatively high risk
travel and pregnancy
