A Case of Successful Treatment of Ruptured Pancreaticoduodenal Artery Aneurysm Caused by Celiac Artery Dissection

: A 52-year-old man was admitted due to severe epigastric lesion pain. Esophagus gastroduodenal endoscopy showed impaired duodenal dilatation, and contrast-enhanced computed tomography revealed a pancreaticoduodenal artery (PDA) aneurysm 13 mm in diameter below the head of the pancreas, retroperitoneal hematoma, idiopathic celiac artery (CA) dissection, and common hepatic artery disruption. Angiographic embolization with a mixture of N-butyl-1,2-cyanoacrylate and lipiodol was performed, and follow-up study showed improvement of the dilatation of the duodenum and disappearance of the aneurysm. Here we report a quite rare case of PDA aneurysm by idiopathic dissection of CA treated successfully with angiographic embolization.
