Objective To investigate the factors of deep vein thrombosis (DVT) of lower extremity after spinal surgery. Methods A total of 100 spinal surgery patients were divided into DVT group (n=39) and non-DVT group (n=161) according to the incidence of postoperative DVT. The general data and surgery-related data of the patients were collected, and the influencing factors of postoperative DVT were analyzed. Results There were significant differences between DVT group and non-DVT group in age, body mass index, diabetes mellitus, blood coagulation, history of intraoperative blood transfusion, operation time, intraoperative blood loss and postoperative bed rest time (P<0.05). Logostic regression analysis showed that age (OR=5.182), blood coagulation (OR=7.477), blood transfusion history (OR=4.010), blood loss (OR=5.708) and postoperative bed rest time (OR=5.445) were risk factors for DVT after spinal surgery. Conclusions The risk of lower extremity DVT after spinal surgery is high. Advanced age, abnormal coagulation function, increased blood loss, perioperative blood transfusion and prolonged postoperative bed rest are closely related to postoperative DVT.
