title: Pancreaticoduodenal artery pseudoaneurysm embolization.
abstract: We report a case of successful transcatheter arterial embolization of a pancreaticoduodenal artery pseudoaneurysm (PSA) caused by erosion of the pancreatic pseudocyst content near pancreaticoduodenal arteries. A 55-year-old man was admitted to a local hospital for investigation of severe, stabbing epigastric pain confined to the upper abdomen. He had a history of previous alcohol abuse, chronic pancreatitis, and a duodenal ulcer. Upper gastrointestinal endoscopy revealed narrowing in the pyloric channel along with an ulcer located at the first and second portions of the duodenum with oozing beneath an adherent cloth and duodenal distortion. Computed tomography additionally revealed an enlarged head of the pancreas with numerous spot calcifications and round cystic formation inside, with a diameter of 30 x 25 mm. Following two surgical procedures for duodenal ulcers, selective angiography revealed a PSA located inside the pancreas head and high-grade stenosis > 90% of the celiac trunk and hepatic artery that rose separately from the aorta. Fiber coil embolization was used to occlude the PSA sac successfully. There was no complication after completion of the last embolic procedure. The patient was doing well after 26 months.
