Prophylactic treatment against deep vein thrombosis has become a routine part of surgical treatment. The indications and the form of prophylaxis selected depend on the patient's individual risk profile, which is determined in turn by a combination of exposing and predisposing risk factors. ⋯ In addition, evidence-based data, recommendations for the duration of prophylaxis derived from official guidelines, and medicolegal aspects are discussed. The development of new anticoagulants is expanding the range of prophylactic methods, which means further in-formation is needed.
