Combination between Dunbar Syndrome and May-Thurner syndrome: A rare case Report

Dunbar syndrome (DS) and May-Thurner syndrome (MTS) are part of a group of rare vascular disorders known as "vascular compression syndromes." Dunbar's syndrome is caused by the median arcuate ligament of diaphragm, which, due to an abnormal course, causes celiac artery compression. MTS is caused by the left common iliac vein compression pushed against the spine by the right common iliac artery causing progressive flow congestion and leading to thrombosis. Ultrasound is the first-level examination for the diagnosis of these rare pathologies and allows to recognize vascular compressions and to obtain an estimate of stenosis degree. We describe a very rare case of DS and MTS combination in a young man with postprandial pain and left lower limb thrombosis.
