INTRODUCTION: Superior mesenteric artery (SMA) syndrome is a rare cause of duodenal obstruction, typically associated with weight loss–related narrowing of the aortomesenteric angle. In contrast, fixed mechanical compression after endovascular aneurysm repair (EVAR) may produce duodenal obstruction that mimics SMA syndrome through a different mechanism.
