Mechanical Compression as an Option for Preventing VTE
Venous thromboembolism (VTE) can be a life-threatening complication of total knee arthroplasty, and it may be even more likely to develop in a patient undergoing a simultaneous bilateral procedure.
Because the optimum VTE prophylaxis in that patient population is unclear, researchers from Washington University in St. Louis, Missouri, compared 2 options based on VTE risk stratification:
- Standard risk: Mobile compression device (MCD) for 10 days followed by aspirin for 6 weeks following surgery
- High risk: Warfarin adjusted for target INR for 4 weeks plus compression stockings for 6 weeks following surgery
In this head-to-head comparison, both treatments were effective, with no VTEs in the 6 months following surgery, leading the study authors to conclude that MCD with aspirin is a safe option for preventing VTEs in patients undergoing simultaneous bilateral TKA. The results were presented at the recent annual meeting of the Mid-America Orthopaedic Association.
