Transarterial Embolization for Ruptured Esophageal Artery Aneurysm Associated with Median Arcuate Ligament Syndrome: A Case Report

Median arcuate ligament syndrome is a rare condition that can lead to aneurysm formation in collateral vessels due to celiac artery compression. While pancreaticoduodenal artery aneurysms are common, esophageal artery aneurysms are extremely rare. We report a case of a ruptured proper esophageal artery aneurysm associated with median arcuate ligament syndrome in a 61-year-old woman. Emergency transarterial embolization using N-butyl 2-cyanoacrylate was performed successfully via the afferent artery. Follow-up imaging confirmed effective embolization with preserved esophageal perfusion and no signs of ischemia. This case highlights the importance of recognizing rare aneurysm sites in median arcuate ligament syndrome, and supports N-butyl 2-cyanoacrylate embolization as a safe and effective treatment for esophageal artery aneurysms.
