MDCT angiography image: partially thrombosed pseudoaneurysm (white arrow) is visible, markedly eroding the vertebral body (black arrow) and compressed liver parenchyma (arrowhead).

Presence of a giant pseudoaneurysm originating from the celiac trunk was confirmed through initial angiography, which was performed via transfemoral approach (Figure 2). A 6x40-mm vascular stent graft (Fluency; Bard-Angiomed, Arizona, USA) was delivered to the celiac artery over a stiff hydrophilic guidewire; following stent-graft implantation, intra-stent-graft balloon dilatation was performed to achieve optimal sealing at the ends of the stent-graft (Figure 2).
Following interventional procedure: control angiogram (A), MDCT angiography (B), and colored Doppler US (C) show exclusion of pseudoaneurysm by the stent-graft.

Control angiography performed at the end of the procedure showed complete exclusion of the aneurysm with no endoleak and preserved celiac arterial flow (Figure 3A). During a three-month follow-up, no endoleak was detected via MDCT angiography (Figure 3B) or Doppler US (Figure 3C); additionally, it was found that normal blood flow through celiac artery was preserved.
