case_images: Jejunal migration of the stent-graft placed for common hepatic artery pseudoaneurysm.. A. Enhanced abdominal CT shows pseudoaneurysm of the common hepatic artery with a wide neck.. B. Celiac arteriogram shows pseudoaneurysm of the common hepatic artery (left); image acquired immediately after stent-graft placement shows preserved hepatic flow, with no extravasation of the contrast agent (right).. C. Enhanced abdominal CT images acquired 2 days after the stent-graft placement show no filling of contrast agent into the pseudoaneurysm (left) and preserved hepatic arterial flow (right).. D. Enhanced abdominal CT image acquired 17 months after the stent-graft placement shows the most of the stent-graft inside the jejunal lumen, surrounded by recurrent mass and lymphadenopathies (arrows).. E. Plain radiograph obtained 18 months after the stent-graft placement shows that the stent-graft (arrow) has moved to the bowel.. F. Enhanced abdominal CT acquired the next day shows the stent-graft (arrow) in the descending colon.

case_images: CHA pseudoaneurysm embedded near the site of the pancreaticojejunostomy (Fig. 1A). Celiac arteriography showed a pseudoaneurysm with a wide neck (13 x 13-mm), arising from the site of origin of the gastroduodenal artery (Fig. 1B). Subsequent celiac arteriography showed no extravasation of the contrast media and preserved hepatic flow (Fig. 1B). CT at 2 days after the stent-graft insertion showed no filling of the contrast media in pseudoaneurysm and preserved distal arterial flow (Fig. 1C). However, CT showed almost every part of the stent-graft locating inside the jejunal lumen with occlusion of common and proper hepatic artery (Fig. 1D). Serial abdominal plain radiography and CT showed that the stent-graft moved to the descending colon and escaped the abdominal cavity (Fig. 1E, F).
