Abstract:

BACKGROUND: Deep vein thrombosis after total knee arthroplasty has attracted increasing attention in recent years, but how to detect deep vein thrombosis in the early time in clinical practice remains unclear. Whether it is necessary to perform type-B ultrasonic or other invasive examination in lower limbs has become a hot issue.

OBJECTIVE: To explore the significance of D-Dimer and fibrin degradation products in the prediction of deep vein thrombosis after total knee arthroplasty.
METHODS: 56 patients received total knee arthroplasty were collected from Department of Orthopedics, The 306th Hospital of Chinese PLA, between December 2012 and February 2014. The D-Dimer and fibrin degradation products were dynamically monitored before operation and at 1, 3, 5, 7, 10 days post-operation. All the patients received type-B ultrasonic examination in double lower limbs at 10 days post-operation, and divided into thrombus group and non-thrombus group. The D-Dimer and fibrin degradation products in the two groups were compared.
RESULTS AND CONCLUSION: Deep vein thrombosis was found in 13 cases by ultrasonic-B postoperation, D-Dimer and fibrin degradation products showed no significant difference between the two groups at 1 week after operation (P > 0.05), but the difference was significant at 10 days (P < 0.01). D-Dimer and fibrin degradation products index should be monitored dynamically for at least 10 days after operation, which is helpful for the early diagnosis of thrombosis.
