Incidence and risk factors of early deep venous thrombosis after posterior cervical surgery-382 cases report

Background: The purpose of this retrospective study was to investigate the prevalence of DVT and identified associated risk factors for DVT in patients admitted to hospital for posterior cervical surgery. Method: In this comparative study, 382 patients admitted for posterior cervical surgery who was allocated to two groups, those who developed DVT (DVT group) postoperatively and those who did not (non-DVT group). To examine the perioperative risk factors for DVT after posterior cervical surgery, comparative analysis of the two groups was done. Result: DVT was detected in 7.1% (27/382) patients, including 1 proximal DVT patients (3.7%) and 26 distal DVT patients (96.3%). According to multivariate logistic regression analysis, the age (P = 0.015, OR 1.026, 95% CI: 0.96311.1536), history of hyperlipidemia and major surgery (P = 0.015, OR 6.221, 95% CI: 1.1243-3.3297; P = 0.013, OR 1.642, 95% CI: 1.0954-2.1510) and D-dimer (P = 0.003, OR 1.542, 95% CI: 1.0236-2.2631) were significant risk factors relative to the onset of DVT after posterior cervical surgery. Conclusion: The incidence of DVT in patients who undergo posterior cervical surgery was 7.1% (27/382). Patients admitted to hospital for posterior cervical surgery with increased age, D-dimer, history of hyperlipidemia and major surgery might be at increased risk for postoperative DVT.
