The well-visualized inferior vena cava (IVC) is average in caliber without intraluminal thrombosis.
There is significant compression of the left common iliac vein against the lumbar vertebrae by the overlying right common iliac artery with subsequent dilatation and congestion of the pelvic and vulval veins. Linear filling defects representing thrombi and/or intraluminal spurs are seen within the dilated segment of the left common iliac vein.
Incidentally, a gastric balloon is noted.
This is a case of May-Thurner syndrome, which a disorder resulting from chronic compression of the left common iliac vein between the overlying right common iliac artery and adjacent lumbar vertebrae. It is usually observed in young women in their 2nd to 4th decades.
