Abstract
BackgroundThe 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).MethodsThe 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.ResultsDVT 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.ConclusionsAccording 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.
Highlights
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)
There were no patients with clinical signs of deep vein thrombosis (DVT) or pulmonary embolism (PE)
The findings of our study indicated that demographics and basic characteristics associated with DVT-positive and DVTnegative group were generally similar, DVT-positive was associated with a significantly high preoperative plasma D-dimer level compared to the DVT-negative group
Summary
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). Conclusions: 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. Venous thromboembolism (VTE) is a common complication of spinal surgery which included deep vein thrombosis (DVT) and pulmonary embolism (PE). There was still got the fear of hemorrhagic disorders and spinal epidural hematoma (SEH) [8]
