Rudolf Virchov 1821 - 1902

Nice Guidelines 2010 Had orthopaedic input Risk assess Hip and knee replacements high risk Combined methods Oral agents (not aspirin) Duration ‘Opt out’ when bleeding risk

Anti-Embolism Stockings

Often problematic for our patients

Wounds, swelling etc Restricted movement Large legs

The importance VTE recognised We have some knowledge of efficacy Variable but increasing prophylaxis

The adverse effects must be considered Expert guidance needed There will be ongoing change
