Flow chart depicting the venous thromboembolism assessment strategy. Patients were evaluated using D-dimer screening, lower extremity venous ultrasonography, and contrast-enhanced computed tomography. A total of 23 patients were not included based on the exclusion criteria. *Additional extensive resections for unplanned resections or positive margins and non-orthopedic surgery patients were included. **Only cases with D-dimer > 1.0 μg/ml and not yet evaluated imaging studies were indicated. a CT: computed tomography; b VTE: venous thromboembolism; c DOACs: direct oral anticoagulant
