Risk factors of deep vein thrombosis after craniotomy
Objective To explore the risk factors of deep vein thrombosis(DVT)after craniotomy.Methods Data from 202 patients who rcceived craniotomy at the Department of Neurosurgery of Jiangsu Provincial People's Hospital between January 2019 and December 2022 were retrospectively analyzed.The patients were divided into two groups based on the occurrence of postoperative DVT.The control group(n= 160)had no DVT,while the case group(n= 42)had DVT.The independent risk factors for DVT after craniotomy were analyzed,and the predictive effect of DVT after craniotomy was analyzed using a logistic regression model.Results Among all the patients investigated,42 patients developed DVT,and the incidence of DVT was 20.79%.The result of univariate analysis showed that there were statistically significant differences in blood loss,absolute bed length after surgery,and the proportion of hypercoagulability between the two groups(P<0.05).The multi-factor model and independent influencing factors were used to predict the occurrence of DVT after craniotomy.The optimal cut-off values were 526.42 ml,9.78 d,0.50,27.15%,and the area under ROC curve was 0.763,0.859,0.730,0.948,respectively.The Yoden index was 62.41%,57.95%,46.04%and 82.47%,respectively.Conclusion Patients with craniotomy have a high risk of DVT after surgery.The establishment of the risk factor analyzer prediction model can better prevent and control this situation,help reduce the risk of patients and increase the success rate of surgery.
