Abstract：【Objective】To investigate the risk factors of DVT in deep vein thrombosis of lower extremity after spinal surgery.【Methods】From August 2014 to August 2016, 246 patients were collected in our hospital for spinal surgery. According to the occurrence of DVT in the lower extremities after operation, the patients were divided into DVT group (n=45) and non-DVT group (n=201). The clinical data, surgical and postoperative factors were compared between the two groups. The influencing factors of DVT after spinal surgery were analyzed by logistics regression analysis.【Results】The incidence of DVT after spinal surgery in this group was 18.29% (45/246). In the comparison of age, body mass index (BMI), diabetes mellitus, preoperative ultrasound results, four items of preoperative coagulation, intraoperative blood loss, intraoperative blood transfusion, operation time, early bed-rest time after operation and physical anticoagulation in the DVT and non-DVT groups, the difference of was statistically significant (P<0.05). Multivariate Logistic regression analysis showed that age, preoperative ultrasound, preoperative coagulation function, intraoperative blood transfusion, early postoperative bed rest and physical anticoagulation were independent risk factors for DVT after spinal surgery.【Conclusion】The elderly, abnormal ultrasound before operation, four items of abnormal preoperative coagulation (more than 2), intraoperative blood transfusion, early postoperative bed time (over 5 d) were independent risk factors of DVT patients after spinal surgery, while early bed activity, physical anticoagulation are protective factors for DVT following spinal surgery.
