INCORPORATING A MECHANICAL SYSTEM OF DVT PROPHYLAXIS IN CLINICAL PRACTICE – 20 YEARS EXPERIENCE IN THE UK ORTHOPAEDIC AND TRAUMA DEPARTMENT



Abstract

Mechanical methods of deep vein thrombosis (DVT) prophylaxis rely on the prevention of venous stasis – one of Virchow’s triad of cause of DVT. Mechanical methods, such as the A-V Impulse System (Orthofix Vascular Novamedix, Andover, UK) are used widely in orthopaedic surgery for the prevention of DVT, especially after elective orthopaedics.

The evidence for the use of the A-V Impulse System in elective orthopaedics is widely accepted and is considered a Grade A Recommendation by the International Consensus Statement. These data are reviewed and critiqued.

More recent studies show how mechanical methods can offer benefits to the patient outside of hip and knee replacement surgery. Data are presented on how such devices can effectively reduce swelling, DVT, compartment pressure and pain associated with trauma, based on over 20 years of practical experience. The practical implications of using these devices is discussed.
