Abstract:

Objective To investigate the incidence of deep venous thromboembolism (DVT) after the operation of the patients with spinal tuberculosis, and to explore the necessity of adopting relevant measures to prevent occurrence of DVT during perioperative period.Methods This study was conducted in 146 patients with spinal tuberculosis who underwent surgery from the same group of physicians and did not receive anticoagulation from May 2012 to August 2017 in Haihe Hospital. Preoperative blood routine examination, coagulation index and double lower limb venous color Doppler ultrasonography were performed; after the operation, the double lower extremity venous color Doppler ultrasound were repeated, and follow-up for 3 months.Results Among the 146 patients who were confirmed to have no DVT before operation, the DVT was found in 11 cases and no pulmonary embolism (PE) cases were diagnosed. The spontaneous incidence of DVT after spinal tuberculosis surgery was 7.53%. All patients with postoperative DVT after 7-10 days of operation had the calf muscle venous thrombosis which located in the far beyond the knee. The patients had no obvious clinical symptoms and did not receive related treatment. The DVT disappeared after 3 months of review of doppler ultrasound.Conclusion In the perioperative period of spinal tuberculosis operation, DVT have a higher natural incidence without anticoagulation. All patients with DVT do not have serious consequences, and the perioperative period of spinal tuberculosis do not need conventional drugs to prevent DVT.
