A Higher Altitude Is an Independent Risk Factor for Venous Thromboembolisms After Total Hip Arthroplasty

摘要

Background: High altitudes lead to physiological changes that may predispose to venous thromboembolisms (VTEs) including deep vein thrombosis and pulmonary embolism (PE). No prior study has evaluated if there is also a higher risk of VTEs for total hip arthroplasties (THAs) performed at higher elevations. The purpose of this retrospective study was to identify if undergoing THA at a higher altitude center (4000 feet above sea level) is an independent risk factor for a postoperative VTE.
