Japanese Study: Incidence of venous thromboembolism and bleeding complications in orthopedic surgery

  • 06



    Orthopedic surgery of the lower extremity including total knee arthroplasty (TKA), total hip arthroplasty (THA), and hip fracture surgery (HFS) are widely considered to carry a high risk of developing deep venous thrombosis (DVT) and venous thromboembolism (VTE) and a Japanese study has investigated this in 36,947 patients who had undergone orthopedic surgeries.

    The researchers Fuji TAkagi MAbe YOda EMatsubayashi DOta K5, Kobayashi MMatsushita YKaburagi JIbusuki KTakita AIwashita M and Yamaguchi T are from 10 institutions in Japan. 



    The source population of the database was derived from 100 acute-care hospitals.  13.6% of the patients ahd total knee arthroplasty. 10.4% for had total hip arthroplasty and 56.8% had hip fracture surgery, 1.5% for rupture of Achilles tendon and 18.0% for simple fracture of lower extremities.



    The incidence for DVT and venous thromboembolism (pulmonary) and bleeding events by type of surgery was :


    Total knee arthroplasty:  DVT 1.3%,  VTE 0.2% and bleeding evetns 1.0%.


    Total hip arthroplasty:  DVT 0.9%, VTE 0.2% and bleeding events 1.1% 


    Hip fracture surgery:  DVT 0.4%, VTE 0.1% and bleeding events 1.8%



    The authors just report these findings as an audit for their Japanese Orthopedic Surgery population.
