ABSTRACT
Objective:To investigate the incidence of lower extremity deep vein thrombosis (DVT) after hip replacement surgery in middle-aged and elderly patients and to explore the risk factors.Methods:A total of 121 middle-aged and elderly patients who underwent hip replacement in the Tianjin People's Hospital from January 1, 2018 to December 31, 2020 were collected for analysis. The basic characteristics of the patients included were statistically described by univariate and multivariate logistic regression analysis.Results:There were 98 male patients and 23 female patients, with an average age of 59.55±9.53 years. 51 patients developed postoperative DVT of the lower limbs, with an incidence of 42.1%. Older age ( OR=1.129, 95% CI=1.013-1.239), body mass index (BMI, kg/m 2) ≥24 ( OR=1.493, 95% CI=1.066-2.314), history of diabetes ( OR=1.293, 95% CI=1.114-2.094), and long postoperative hospital stay ( OR=1.203, 95% CI=1.056-1.377) were risk factors. Conclusions:The risk of lower extremity DVT after hip replacement surgery was higher in middle-aged and elderly patients. In clinical practice, we should pay attention to risk factors and focus on key groups to prevent the occurrence and development of lower extremity DVT.
