Background:
Deep vein thrombosis (DVT) is the main cause of pulmonary thrombolism (PE). Thus by preventing DVT, the risk of PE can be greatly reduced.
Methods:
Patients were divided into two groups: a group of patients who were affected with DVT after total hip arthroplasty (THA) and a group of patients who were not affected. To examine the risk factor for DVT after THA, a comparative analysis between these two groups was performed.
Results:
According to the multivariate logistic regression analysis, the preoperative elevated value of D-dimer is a significant risk factor which is only relative to the onset of DVT after THA. In addition, it was suggested that the preoperative value of D-dimer could be used as a means to rule out DVT after THA.
Conclusions:
It is useful to investigate the preoperative value of D-dimer as a predictive factor for the occurrence of DVT after THA.
