Successful embolization assisted by covered stents for a pseudoaneurysm following pancreatic surgery

Figure 2 Placement of covered stent graft for pseudoaneurysm of common hepatic artery. A: Angiography revealed a pseudoaneurysm arising at the common hepatic artery (white arrows) and the dilated lumen of the common hepatic artery (arrowheads); B: A guide wire was advanced past the pseudoaneurysm and a 4 mm x 14 mm covered stent was deployed (arrows); C: Angiography revealed extravasation of contrast medium from the proximal edge of the covered stent (arrow). A dehiscence seemed to occur at the fragile arterial wall; D: An additional covered stent (arrows) was placed partly under lapping the first stent (black arrows).
