May–Thurner Syndrome after Total Knee Arthroplasty

  • 1Department of Orthopaedic Surgery, Dona-A University College of Medicine, Busan, Korea


Iliac vein compression syndrome, which results in thrombosis of the left iliac veins, was first described by May and Thurner in 1957. May– Thurner syndrome should be considered when deep vein thrombosis-like symptoms appear, especially in the left lower extremities without an invasive procedure. The authors encountered an interesting case of a middle-aged female patient, who presented with sudden pain, swelling and skin color changes to the left lower extremity after right total knee arthroplasty and was diagnosed May–Thurner syndrome by computed tomography venography. This case is of clinical significance in that the early diagnosis of May–Thurner syndrome in the left lower extremity was made, which might have been overlooked after right total knee arthroplasty. This case is reported with a review of the literature review.
