Pelvic acetabular fractures(PAFs) are one of the most common types of pelvic fractures, mostly high-energy injuries, with complex pelvic acetabular structure and limited surgical methods. The trauma of the acetabular fracture itself and the need for long-term bed rest after surgery cause particularly complicated clinical complications. Venous thromboembolism (VTE) is one of its high incidence and serious complications. This review mainly focuses on VTE after PAFs, and describes the epidemiology, risk factors and prevention measures of VTE, aiming to help improve the prognosis and avoid the occurrence of serious complications.
