Prevention of Venous Thromboembolic Events following Femoroacetabular Osteoplasty: Aspirin is Enough for Most

Abstract

Aspirin is a safe and effective modality to provide thromboprophylaxis in patients undergoing hip-preservation surgery. The rate of VTE that we observed is, thus far, the lowest in comparison to other published series of hip preservation surgery that specifically focused on this complication.

Venous thromboembolism prophylaxis after hip preservation surgery: a review and presentation of institutional experience

“…However, multiple bone osteotomies during PAO may predispose patients for subsequent bleeding and a potent anticoagulation may increase the risk of bleeding [ 50 , 51 ]. On the other hand, because of the partial or non-weight bearing status of the patient after this procedure, some degree of inactivity and limb swelling occurs that may predispose the patients to VTE [ 16 , 52 ].…”

“…The only study that evaluates the incidence of VTE after min-open FAO is by Tischler et al [ 16 ]. In a prospective case series of 407 consecutive patients who underwent mini-open FAO procedure, the rate of symptomatic VTE was 0.25% when aspirin at 325 mg daily dose was administered.…”

“…The frequency of venous thromboembolic disease during the post-operative period of patients undergoing PAO has been reported to between 0 and 5% [ 9–13 ]. Similarly the rate of VTE after hip arthroscopy has been reported to be between 0 and 9.6% [ 14 , 15 ], 0.25% after mini-open FAO [ 16 ] and 0.5% after SDH [ 17 ] using different VTE prophylaxis protocols.…”

Recommendations from the ICM-VTE: Sports

“…There were no significant differences in symptomatic VTE rates in patients receiving warfarin, aspirin (ASA) 325 mg or ASA 81 mg, with no events of bleeding or hematoma formation 120 . In a prospective case series of 407 consecutive patients who underwent mini-open FAO procedure, Tischler et al 123 , found that the rate of symptomatic VTE was 0.25% when ASA 325 mg daily dose was administered. The majority of the patients included in this cohort were young, healthy and active, and were ambulated within hours of their surgery 123 .…”

The majority of the patients included in this cohort were young, healthy and active, and were ambulated within hours of their surgery 123 . Based on institutional experience, a review study from the Rothman Institute recommended that ASA 81 mg two times daily is a safe and effective modality in minimizing the risk of VTE in patients undergoing hip preservation surgery 119 .…”
