Fig. 1From: Plasma D-dimer is not useful in the prediction of deep vein thrombosis after total knee arthroplasty in patients using rivaroxaban for thromboprophylaxisLongitudinal changes of the D-dimer levels after TKA.

The D-dimer levels were significantly higher in patients with DVT than in patients without DVT on POD4Back to article page
