Risk factors of thromboembolic complications in the patients in need of planned endoprosthetics of the hip or knee

Abstract

Most patients hospitalized for the hip or knee replacement have 1-3 additional risk factors of venous thrombosis and embolism. The age (above 40 years old), obesity, chronic non-specific lung diseases, varicose disease of the lower limbs are the most frequent factors. The routine use of anticoagulant prevention of thromboembolic complications combined with regional anesthesia is safe and allows to reduce the lethality caused by pulmonary thromboembolism significantly (0.007 %) after the planned replacement of the hip or knee.
