Effectiveness of Deep Venous Thrombosis Prevention in Total Hip Arthroplasty

Abstract

Objective: To determine the efficacy of Deep Venous Thrombosis (DVT) prophylaxis protocol in patients undergoing total hip arthroplasty (THA), and to verify differences in the rates of this complication when comparing primary replacement surgeries with revision surgeries. Methods: We conducted a retrospective study of patients operated between 2012 and 2018, with inclusion and non-inclusion criteria determined by the researchers. A protocol was created to compile data including 92 patients, amounting to 110 operated hips, divided by gender, age, laterality, among other criteria. For THA cases, low molecular weight heparin chemoprophylaxis was used, associated with the use of pneumatic and elastic compression, concomitant to deambulation as soon as possible. The detection of DVT was determined by clinical evaluation and imaging exams such as: simple radiographs, ultrasound, arterial and venous color doppler, and laboratory tests. Results: The use of the protocol was very effective in our study. Only one (1.09%) case of deep venous thrombosis was found. Conclusion: The use of thromboprophylaxis for DVT is indispensable, as was clearly demonstrated by these cases. We observed only one (1.09%) case of DVT in our series. Level of Evidence III, Retrospective Study.

Correlation analysis of Blood TM, TG and D-dimer with deep venous Thrombosis formation in patients after Total Hip Arthroplasty

“…2 According to previous studies, DVT formation may occur in over 30% of patients undergoing THA postoperatively, which is generally related to factors such as peripheral vascular injury and vessel intimal injury caused by surgery. 3 In the absence of effective control, pulmonary embolism will occur in patients with serious progress, which may be life-threatening. DVT is characterized by occult onset and low diagnostic rate using conventional Doppler ultrasound, resulting in the lack of effective control of the occurrence of DVT.…”

Effect of Low Molecular Weight Heparin on Prevention and Treatment of Deep Venous Thrombosis in Elderly Patients With Hip Fracture After Operation

“…Deep venous thrombosis (DVT) formation refers to abnormal coagulation of blood in the deep veins of the lower extremities, resulting in impaired blood return and symptoms such as limb swelling and pain [1][2][3]. In recent years, with the increase in the ageing population, the incidence of hip fractures in the elderly has shown an increasing trend, and data have shown that hip fractures are a high-risk factor for DVT formation [4][5][6]. Relevant studies have found that the incidence of DVT in patients after hip surgery is about 13% in China and worldwide [7][8][9].…”
