Cross-sectional CT scan demonstrates large abdominal aortic aneurysm compressing Inferior Vena Cava (IVC). The arrow points to juxta-renal IVC, the arrow head points to the virtually occluded IVC, and the line to the thrombosed common iliac veins.

Computed Tomography (CT) demonstrated a compression of the IVC by an AAA moderately developing to the right, with apparent collapse and caudal thrombosis and a nonfunctioning right kidney (urea and creatinine blood levels remained within a normal range) (Figure 1).
(a) Inferior vena cavagram performed through jugular approach demonstrates collapse of IVC at the AAA level (Black arrows). (b) Operative photograph shows IVC (white arrow) compressed medially and anteriorly by AAA. (c) Eight-month-postoperative coronal CT reconstruction shows patency of the vascular graft and of the IVC at filter level and cranially.

IVC filter was placed infrarenally through transjugular access. Inferior vena cavagram performed before the deployment of the filter, confirmed the collapse of the IVC (Figure 2(a)). AAA were observed (Figure 2(b)). After having opened the aneurysm sac, the thrombus was removed in an attempt to decompress the IVC. IVC at filter level and cranially (Figure 2(c)). Iliac veins were partially recanalized, but IVC adjacent to the remaining aneurysm sac continued apparently collapsed.
