Abstract

Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by a decreased aortomesenteric angle that causes a duodenal obstruction. Various medical and psychiatric conditions may result in the initial rapid weight loss that causes narrowing of the aortomesenteric angle. Isolated dissection of the superior mesenteric artery (DSMA) is an uncommon cause of acute mesenteric ischemia. Several literature reports suggest that medical treatment in combination with close observation is reasonable in uncomplicated dissection with stable hemodynamic status. Recently, as several reports describe, rapid revascularization by percutaneous angioplasty and endovascular stent insertion can prevent bowel ischemia that progresses to irreversible bowel necrosis. However, the stability of endovascular stents at the DSMA has not been confirmed, because its use is reasonably infrequent. Here, we report a case of SMA syndrome, as a complication of endovascular stent placement at the DSMA.
