Image findings in celiac artery stenosis due to median arcuate ligament compression: a crucial diagnosis when planning for pancreaticoduodenectomy.

Celiac axis stenosis caused by extrinsic compression by the median arcuate ligament (MAL) is present in up to 5% of patients undergoing pancreaticoduodenectomy. Failure to identify and manage MAL compression can lead to potentially devastating postoperative consequences that include frank liver necrosis and death. We report an incidental discovery of celiac axis stenosis by MAL in a patient prepared for pancreaticoduodenectomy.
