Abstract
An inferior pancreaticoduodenal arterial (IPDA) aneurysm was incidentally pointed out in a 43-year-old man by computed tomography (CT) for examination of another disease. CT and angiography showed a 12-mm saccular type IPDA aneurysm and severe stenosis of the celiac axis by median arcuate ligament, and celiac axis compression syndrome (CACS). It also showed that the IPDA was a good collateral pathway for the celiac artery. Therefore, it was important to prevent perioperative ischemia of the abdominal organs. First, we divided the median arcuate ligament, and subsequently resected the IPDA aneurysm. After surgery the patient recovered without significant incident. We believe that it is necessary to organize the strategy for surgical treatment for IPDA aneurysm with CACS.
