The purpose of this study aimed to assess preoperative risk factors for the incidence of deep venous thromboembolism in patients undergoing posterior lumbar interbody fusion (PLIF). The diagnosis of preoperative deep vein thrombosis (DVT) was confirmed by Doppler ultrasonography. To examine the preoperative risk factors for DVT admitted for PLIF, comparative analysis of the DVT-positive and DVT-negative groups was done. DVT was detected in 9.4 % (269/2861) patients, including 17 proximal DVT patients (6.3 %) and 252 the distal DVT patients (93.7 %). According to multivariate logistic regression analysis, the age, preoperative D-dimer, and history of rheumatoid arthritis were significant risk factors relative to the onset of DVT after posterior lumbar surgery. According to the result of our study, age, positive preoperative plasma D-dimer level, and rheumatoid arthritis had the influential impact on the incidence of DVT admitted for PLIF.
