A Retroperitoneal fibrosis demonstrated at CT scan B Aorto-caval fistula originating from the abdominal aorta below the renal arteries (double arrow). The inferior vena cava (arrow) was completely occluded few centimetres above the communication with the aorta.

A CT scan was performed that evidenced retroperitoneal fibrosis (figure 1A) as well as an aorto-caval fistula involving the abdominal aorta below the renal arteries (figure 1B). The inferior vena cava was completely occluded few centimetres above the communication with the aorta (figure 1B).
The CT scan at 1 month follow-up after vascular plug implantation showed recurrence of the aorto-caval communication. The Amplatzer vascular plug, still in correct position, was not able to halt the fistulous communication.

The CT scan also showed the Amplatzer vascular plug still in correct position (fig. 2).
The CT scan 1 month after aortic endoprosthesis implantation showed a complete abolishment of the shunt with no opacization of the inferior vena cava from the abdominal aorta . The Amplatzer vascular plug was excluded from the aortic blood flow after the endoprosthesis implantation.

The CT scan performed one month later showed a complete abolishment of the shunt with no opacization of the inferior vena cava from the abdominal aorta (Figure 3). The Amplatzer vascular plug was excluded from the blood flow after the endoprosthesis implantation (Figure 3).
