Association of Dunbar, May-Thurner and Nutcracker Compression Syndromes in One Patient

We report a case of Dunbar syndrome, May–Thurner syndrome and Nutcracker syndrome diagnosed in one patient with clinical presentation and imaging findings on Doppler ultrasonography. Dunbar syndrome or truncus coeliacus compression syndrome is an under-diagnosed vascular compression syndrome with a lot of controversy around it because of insufficient differentiation from celiac artery stenosis. May–Thurner syndrome or iliac vein compression syndrome is an anatomically variable condition of venous outflow obstruction caused by extrinsic compression by the right common iliac artery as it crosses the iliac vein anteriorly. In Nutcracker syndrome due to compression the outflow from the left renal vein into the inferior vena cava is obstructed. The combination of all these syndromes in one patient was not described before.
