• ABSTRACT
    • Venous thrombotic events frequently complicate major elective arthroplasties such as hip and knee replacements. The risk of proximal deep vein thrombosis and pulmonary embolism is estimated at 5 %. For decades, the use of low-dose heparins for up to 5 weeks post-surgery has helped to reduce the risk of thrombotic complications. In this narrative review, we describe the evidence supporting the use of direct oral anticoagulants (in Switzerland - rivaroxaban and apixaban), whose risk-benefit ratios appears superior to that of heparins, at a lower cost. Hybrid strategies combining a short-term anticoagulant followed by low-dose aspirin are also recommended for patients deemed at low thrombotic risk.
