광범위 심부정맥혈전증에 자발성 자궁난소정맥 파열에 의한 복막외 혈종이 동반된 May-Thurner Syndrome 1례

Abstract

May-Thurner syndrome, also known as iliac vein compression syndrome, is an anatomically variable condition that is characterized by left common iliac vein compression by the right common iliac artery and the lumbar vertebra. This chronic and pulsatile venous compression by the right common iliac artery can cause local intimal injury, inflammation, scarring, and fibrosis, leading to venous outflow obstruction and increased intraluminal pressure. This can cause several complications, such as venous insufficiency, venous claudication, deep vein thrombosis, and very rarely extraperitoneal hematoma due to spontaneous iliac vein rupture. In particular, in middle aged women, hormonal imbalance coupled with these mechanical and inflammatory factors can cause further weakening of the venous wall integrity and develop spontaneous and potentially lethal venous rupture. This paper reports an extremely rare case of a 58-year-old woman with May- Thurner syndrome with acute and extensive deep vein thrombosis of the left lower extremity and a spontaneous extraperitoneal hematoma caused by utero-ovarian vein rupture.
