Stent-graft implantation to treat an inferior vena cava aneurysm

To present a patient with a primary inferior vena cava aneurysm who was subjected to endovascular treatment.

A 60-year-old man, suffering from pulmonary embolism, was diagnosed with a vena cava aneurysm located below the renal veins. Through the right common femoral vein, a custom-made stent-graft was implanted. Proximal and distal barbs were incorporated in the frame to assist fixation and avoid caudal or cephalad migration. The procedure was performed without any technical or clinical complications, and the aneurysm was completely excluded from the circulation. During the 6-month follow-up, imaging verified the correct position of the stent-graft and exclusion of the aneurysm without endoleak or any other complication.

In patients with inferior vena cava aneurysm, stent-graft implantation may be an alternative to open surgery.
