Abstract

Two female patients (74 and 80 years old) underwent revision total knee arthroplasty surgery due to aseptic loosening. Patient 1 was obese, while patient 2 had history of abdominal surgery, cerebrovascular and autoimmune disease. They were both under anti-depressive medication. Intravenous tranexamic acid was administrated according to institutional protocol. Knee mobilization and enoxaparin in prophylactic dose was initiated at day 1 postoperatively. Both patients had pulmonary thromboembolism within the first 30 days after surgery. Individual risk factors predispose to pulmonary thromboembolism, while tranexamic acid way of administration does not seem to be responsible for the risk increase.


Individual risk factors predispose to pulmonary thromboembolism, while tranexamic acid way of administration does not seem to be responsible for the risk increase.
