Emergency embolization of a ruptured aneurysm of the pancreaticoduodenal arcade.
Inferior pancreaticoduodenal aneurysms are uncommon. A 77-year-old woman was seen with a 1-week history of sharp pain in the right lower abdominal quadrant radiating to the back, associated with malaise, anorexia, vomiting and nonbloody diarrhea. Appendicitis was diagnosed, but at laparotomy a large retroperitoneal hematoma was found; no aneurysm was identified. The abdomen was closed and aortography was done. An aneurysm of the inferior pancreaticoduodenal artery arcade was demonstrated, with occlusion of the celiac artery at its origin. The arc of Buehler was patent and enlarged and supplied the hepatic and splenic arteries. Embolization with Gianturco coils placed proximal to the aneurysm was successful.
