Rupture of a Pancreaticoduodenal Arterial Aneurysm into the Duodenum Complicated with Celiac Artery Stenosis Caused by Compression of the Median Arcuate Ligament

Abstract

A contrast abdominal computed tomography (CT) scan indicated the rupture of a pancreaticoduodenal arterial aneurysm into the duodenum with celiac artery stenosis in a 56-year-old woman with acute abdomen and vomiting of fresh blood. Catheter embolization was performed for the aneurysm, but was unsuccessful. Therefore, ligation of the inflow vessels and resection of the median arcuate ligament were performed after laparotomy. After surgery, contrast abdominal CT confirmed a decrease in the size of the aneurysm and improvement in the celiac artery stenosis. The patient did not develop any postoperative complications and was discharged on day 22 of hospitalization. Several studies have reported a pancreaticoduodenal arterial aneurysm complicated with celiac artery stenosis; however, rupture of a pancreaticoduodenal arterial aneurysm into the duodenum complicated with celiac artery stenosis has seldom been reported.
