Incidence and influencing factors of deep vein thrombosis after direct anterior approach total hip arthroplasty

Abstract

Background: Deep vein thrombosis (DVT) is one of the common complications after total hip replacement (THA). The direct anterior approach (DAA) total hip arthroplasty is widely promoted and used in clinical practice.The purpose of this study was to investigate the incidence and influencing factors of DVT after DAA-THA. Methods: From January 2021 to November 2022, 168 patients who underwent DAA-THA were selected.These patients underwent the lower extremity doppler ultrasound examination before surgery, 3 days, 14 days, and 30 days after surgery. According to the results of postoperative ultrasound examination, patients were divided into DVT group and non-DVT group.The personal characteristics and clinical data of the two groups were compared and analyzed. Results: The incidence of DVT after DAA-THA was 17.86% ( n = 30 ). Univariate analysis demonstrated that there were significant differences between DVT group and non-DVT group in gender (P=0.014), age (P=0.018), varicose veins (P=0.031) and blood transfusion (P=0.022). After adjustment by using logistic regression analysis,gender appeared to be the independent risk factor for DVT after DAA-THA (P = 0.021, OR = 3.1, 95%CI 1.2–8.3). Conclusions: We found that gender was significantly associated with DVT after DAA-THA,with more females than males.In clinical practice, doctors should pay attention to the influencing factors of DVT to prevent the occurrence of DVT after DAA-THA.
