Management

DVT

A
  1. likely to have it based on Well’s score:
    1. Take D-dimer, 24hr dose parenteral anticoagulant, USS of proximal leg vein
  2. Anticoagulation: Heparin/rivaroxaban whilst waiting for warfarin to increase INR to target range, DVT’s not above knee can be observed and anticoag for 3 months, DVT beyond knee need anticoag for 6 months; recurrent DVT need long term warfarin
  3. IVC filter: if anicoag contraindicated and risk of embolisation
  4. Prevention: graduated compression stockings, mobilisation prophylactic heparin
