[4] [7] [8] For cancer-associated VTE, full-dose DOACs are now preferred over LMWHs, unless there are gastrointestinal lesions that increase the risk of bleeding.
The type of surgery performed prior to the formation of blood clots influences the risk. Without prophylactic interventions, the calculated incidence of clot formation in the lower leg veins after surgery is: 22% for neurosurgery; 26% for abdominal surgery; 45% for 60% in orthopedic surgery; 14% for gynecologic surgery [13]
A patient taking anticoagulants—aspirin, clopidogrel, ticagrelol and others—will stop taking them several days before, to prevent excessive bleeding during and after the operation.
