One, Two, Three: Stepwise Treatment of a Large DVT in a 53 Year Old Femalewith May-Thurner

In 1908, McMurrich described the presence of strictures in the common iliac vein that were believed to be responsible for the increased incidence of left leg deep-vein thrombosis (DVT). This syndrome would eventually become known as iliac vein compression syndrome or May-Thurner Syndrome (MTS). Left iliac vein compression from the contralateral right common iliac artery, against the posterior fifth lumbar vertebral body, is estimated to comprise 49% to 62% of cases of left lower extremity disease.
