Other Known Aliases – Illiac vein compression syndrome
Definition – Compression of the left common illiac vein by the right common illiac artery
Clinical Significance – This anatomic compression causes extensive deep venous thrombosis of the left lower extremity and is the cause of up to 5% of all spontaneous DVT occurrences. It is more common in women (3x) and classically presents in the 2nd to 4th decade of life. This should be considered in any patient with a spontaneous DVT and no other hypercoagulable causes.
History – Named after May and Thurner in 1957 after they published their findings and built on the work of James McMurrich, who was an anatomist at the University of Michigan, and published his anatomic description of this phenomenon in 1908. It was further defined clinically by Cockett and Thomas in 1965, but the eponym goes to May and Thurner. There really is not a lot written about May and Turner and my internet detective skills did not turn up much on these physicians, so I apologize in advance for the paucity of personal information on these physicians that I usually try to provide on these posts.
