Ahmed O, Kim YJ, Patel M, et al. - The present study was performed to ascertain the efficacy and safety of inferior vena cava filters (IVC) filters in preventing pulmonary embolism (PE) in high-risk patients undergoing hip or knee arthroplasty. Between January 2013 and December 2018, researchers retrospectively examined 2,857 hip or knee arthroplasty procedures. They classified patients with a pre-operative history of venous thromboembolism (VTE), either PE or DVT, as high-risk patients. It was shown that the use of IVC filters is significantly correlated with a lower incidence of pulmonary embolism in high-risk arthroplasty patients. The findings revealed that the high-risk patients indicated an incidence of postoperative VTE over two times greater than other patients. In hip/knee arthroplasty, prophylactic placement of IVC filters is safe.
