Superior mesenteric artery (SMA) syndrome is an unusual form of duodenal obstruction. Complications of SMA syndrome may sometimes develop and are usually associated with marked gastric dilatation, although most complications can be corrected by supportive treatment. In this article, we report a case of severe SMA syndrome with hypovolemic shock in a 24-year-old man. Multidetector-row computed tomography with reconstructed images was performed to establish the diagnosis. Spontaneous gastrointestinal bleeding is an extremely uncommon complication of SMA syndrome, and emergent surgical intervention was unavoidable in our patient. To our knowledge, no other such case has been reported in the English-language literature.
肠系膜上动脉（SMA）综合征是一种罕见的十二指肠梗阻形式。SMA综合征的并发症有时会出现，通常与明显的胃扩张有关，不过大多数并发症可通过支持治疗得到纠正。在本文中，我们报告了一例24岁男性患有严重SMA综合征并伴有低血容量性休克的病例。通过多排螺旋计算机断层扫描及重建图像来明确诊断。自发性胃肠道出血是SMA综合征极其罕见的并发症，在我们的患者中紧急手术干预不可避免。据我们所知，英文文献中尚未报道过其他此类病例。
