RESUMO
Venous thromboembolism (VTE) is a notable contributor to the morbidity and mortality of patients with orthopaedic trauma. Several associations have published guidelines on VTE prophylaxis, with a strong predilection toward low-molecular-weight heparin for chemoprophylaxis. However, previous recommendations may be revisited because recent high-level evidence demonstrated aspirin to be noninferior to low-molecular-weight heparin in preventing serious complications of VTE. Direct oral anticoagulants are emerging as safe alternatives to injectable medication and may offer improved patient compliance. There is no consensus on postinjury duration of chemoprophylaxis as an outpatient. Mechanical prophylaxis remains an important adjunctive VTE preventive measure for inpatients with pelvis and extremity fractures. Proteomics and novel laboratory measurements may be able to predict high-risk patients and detect early thrombus formation. Despite high-quality prospective research over the past decade, we still have much to learn about patient- and injury-specific risk factors.
