Calcification in the Inferior Vena Cava

Patency and Clinical Outcome After Stent Placement for Chronic Obstruction of the Inferior Vena Cava

“…In addition to patients with a previously verified IVC thrombosis, baseline image findings of calcification or a fibrous string in the path of an otherwise not detectable IVC, were defined as post-thrombotic IVC obstructions. 35,36 Patients with no history of a previous thrombotic event, no signs indicating post-thrombotic changes on CT imaging, or imaging showing atresia or absence as in congenital abnormalities of the IVC were defined as not post-thrombotic IVC obstructions. IVC occlusion was defined as no contrast filling of the IVC on venography during the stent placement procedure, whereas stenosis was defined as a !…”

Calcified External Iliac Vein Thrombosis

“…Calcification of the inferior vena cava as an amorphous calcified mass has been described in children (1,2) as well as calcified thrombosis of the portal system (3, 4). A precise etiology has not yet been determined, but dehydration has been felt to playa possible role in thrombosis of the inferior vena cava (1,2).…”

“…Other forms of venous calcifications are much less frequent, but have been reported in the inferior vena cava in children (1,2), in the portal venous system (3, 4), and in arteriovenous malformations and vein of Galen aneurysm (5). Iliac vein calcification, however, has not been described previously.…”
