Ostial stenosis of the superior mesenteric artery (SMA) is usually a benign finding due to the significant collateralization inherent with visceral vessels. There is a subset of patients, however, with significant atherosclerotic disease leading to in situ thrombosis and subsequent mesenteric ischemia requiring intervention. Over the last 20 years, management of mesenteric ischemia-acute or chronic-has transitioned from an open embolectomy or bypass to an endovascular-first approach involving angioplasty and stenting. We are reporting a unique case of recurrent SMA stent fracture with imaging demonstrating diaphragmatic compression of the SMA during the respiratory cycle, subsequent management, and recommendations for future intervention.
