INTRODUCTION: Median arcuate ligament syndrome (MALS) is characterized by chronic mesenteric ischemia resulting from external compression of the celiac artery (CA). While rare, this compression can alter local hemodynamics, potentially leading to the formation of visceral artery aneurysms. Although pancreaticoduodenal artery (PDA) aneurysms are a known collateral complication, the concurrent presentation of a poststenotic CA aneurysm and a collateral PDA aneurysm is exceedingly rare. We report the long-term outcomes of a patient with MALS complicated by simultaneous aneurysms of both the CA and the PDA.
