A Case of May-Thurner Syndrome with Systemic Lupus Erythematosus in Antiphospholipid Syndrome

항인지질 증후군을 동반한 전신홍반루푸스에서 진단된 May-Thurner 증후군

May-Thurner syndrome, which refers to an iliofemoral venous thrombosis caused by chronic compression of the left common iliac vein by the right common iliac artery, usually manifests as left lower extremity pain and swelling. The syndrome is particularly evident in patients with health conditions including obesity, smoking, pregnancy, surgery, or prolonged immobility. Antiphospholipid syndrome consists of arterial or venous thrombosis and the association of lupus anticoagulant or anticardiolipin antibodies. Most common clinical manifestations include pregnancy loss and deep vein thrombosis. We experienced a rare case of May-Thurner syndrome concurrent with antiphospholipid syndrome, secondary to systemic lupus erythematosus. The patient was treated successfully by catheter-directed percutaneous thrombectomy, venous thrombolysis, and stent insertion, followed by oral anticoagulant therapy.

항인지질 증후군이 동반된 전신홍반루푸스 환자에서 May-Thurner 증후군이 진단된 예는 아직 세계적으로 보고가 없다. 본 증례와 같이 전신홍반루푸스를 가진 젊은 환자에서 좌측 하지에 심부정맥 혈전증이 발생한 경우 항인지질 증후군을 감별하여야 하며 동시에 May-Thurner 증후군도 감별진단에 포함시켜야 한다. 그리고 진단 이후의 적극적인 혈관중 재시술과 지속적인 항응고제 치료를 통해 재발을 방지하기 위한 전략이 필요할 것이다.
