VTE prophylaxis - leg casts


  • Lower limb immobilisation (even transient) significantly increases the risk of VTE
  • This is particularly so in those with a predisposition to coagulopathy
  • There is no evidence of increased risk in upper limb immobilisation


  • No strong evidence to support oral anticoagulation
  • When indicated, LMWH is effective in preventing VTE
  • If started, continue LMWH until PoP is removed
