摘      要：Background: The relationship of preoperative D-dimer and Venous thromboembolism (VTE) after total knee arthroplasty (TKA) and total hip arthroplasty (THA) remains controversial. The purpose of this study was to assess the value of D-dimer in the detection of early VTE after TKA and THA. Materials and Methods: A total of 312 patients were evaluated in this retrospective study from 2016 to 2020 at a tertiary care centre, Mumbai who were operated for THA and TKA. The measurement of plasma D-dimer level was done preoperatively and clinically symptomatic patients were evaluated and confirmed for VTE by Colour Doppler Sonography. The plasma D-dimer levels were correlated statistically with the sonographic VTE. Results: 11 patients developed Deep Vein Thrombosis (DVT) and 1 patient developed Pulmonary embolism (PE). Preoperative plasma D-dimer levels were significantly higher (P (pelvic and femoral veins), and 2 thrombi were seen in distal veins (posterior tibial, peroneal, gastrocnemian veins) of the calf in THA patients, and all 8 thrombi were seen in the distal veins (posterior tibial, peroneal, gastrocnemian veins) of the calf in TKA patients. Conclusion: We infer that if the preoperative D-dimer levels were more than 0.5 mg/l, the chances of developing VTE postoperatively are more, which can be diagnosed clinically and further by other investigations. In this study, we have shown that doing preoperative D-dimer level can almost PREDICT the development of VTE and thus prevent complications.
