Pancreaticoduodenal Artery Aneurysm Ruptured into Duodenum, Associated with Celiac Trunk Stenosis. Case report and Review of Literature

Pancreaticoduodenal artery (PDA) aneurysm associated with a celiac artery (CA) occlusion or stenosis is an uncommon event. We report the case of a 63-years old man who presented with acute abdominal pain radiating to the back. During the hospital stay, the patient had an episode of severe hematemesis. He had a gastroscopy and then a surgical exploration. However only with arteriography we found a PDA, which had ruptured into duodenum. The aneurysm was associated with a stenosis of the celiac trunk and was supplied by a dense network of collateral vessels from the SMA. The patient was successfully treated with embolization and was discharged on the 64th postoperative day. Short term and mid term follow-up was uneventful. This case shows the difficulty in diagnosing these rare events in time, indicating that angiography is indispensable to establish a diagnosis and enable nonsurgical treatment
