A 20-year-old woman underwent hip arthroscopy with a labral repair, a femoral neck osteoplasty, and acetabular rim trimming. Six weeks after surgery, she presented with leg pain and edema, and was found to have an extensive deep vein thrombosis (DVT). Additional imaging studies revealed apparent extrinsic compression of the left common iliac vein, a vascular anatomic variant consistent with May-Thurner syndrome (MTS).
Thromboembolic events in patients undergoing low-risk procedures should raise concern for additional risk factors, including MTS. Identifying this variant in patients is important to prevent future thrombotic complications.
