Fig. 6. SG placement for pseudoaneurysm after pancreaticoduodenectomy. (A, B) Enhanced CT and 3D image shows pseudoaneurysm at the RHA (anterior segment artery stump) (arrows). (C) Celiac artery angiography shows pseudoaneurysm at the tortuous RHA (anterior segment artery stump) (arrow). (D) The stent delivery system is advanced distal to the pseudoaneurysm along with a stiff 0.018-inch guidewire via a 6-Fr guiding sheath (arrowheads). (E) Stent-graft (VIABAHN®, 6-mm diameter, 50-mm–long) is deployed across the neck of the pseudoaneurysm, and balloon dilation is performed from the distal to the proximal portion of stent-graft to prevent the endoleak (arrowheads). (F) Angiography shows the disappearance of the pseudoaneurysm (arrow). (G) 3D image of enhanced CT performed on the next day shows the patent SG and intrahepatic arteries (arrow). SG, stent graft; CT, computed tomography; RHA, right hepatic artery.
