Damodar D, et al. - Researchers aimed to identify whether undergoing total hip arthroplasties (THAs) at a higher altitude center (>4,000 feet above sea level) was an independent risk factor for a postoperative venous thromboembolisms (VTE). When compared to matched patients receiving tTHAs at a lower altitude (<100 feet), THAs performed at higher altitudes (>4,000 feet) had a higher rate of acute postoperative pulmonary embolism (PEs) in the first 30 days, and also 90 days postoperatively. For these increased risks, THA patients at high altitude ought to be counseled.
