Several modifications to traditional surgical approaches for total hip arthroplasty (THA) have been introduced in an attempt to improve upon minimally invasive approaches and enhance short-term recovery. However, minimally invasive approaches are not without risk, including that of postoperative venous thromboembolism (VTE). There has been no published literature evaluating the femoral vein during an anterior approach. We aimed to study femoral vein blood flow using duplex ultrasonography during THA performed through a modified Heuter approach. Peek flow and vessel cross-sectional area were affected by limb position as well as acetabular and femoral retractor placement. No VTE was observed, but there was observed femoral vein compression, which may represent a risk of postoperative VTE similar to that seen in standard surgical approaches for THA.
