About this study

Avoiding Risks of Thrombosis and bleeding in Surgery (ARTS) trial is a pragmatic, international, multicenter, randomized controlled open label trial comparing a direct oral anticoagulant (DOAC) - oral factor Xa inhibitor apixaban - to no anticoagulant among 5,436 patients undergoing abdominal or pelvic surgery at sufficiently similar (and not high) risk of venous thromboembolism (VTE) and bleeding that the net impact - benefit or harm - of thromboprophylaxis remains in doubt.
