Isolated spontaneous dissection of the superior mesenteric artery (SMA) without aortic dissection is a rare cause of acute mesenteric ischemia. A sudden decrease of intestinal blood flow can lead to fatal complications such as ischemic necrosis, shock, and death. Therefore, early diagnosis and therapeutic approach before the occurrence of intestinal infarction are the most important factor to determine the patients prognosis. A 52-year-old male presented with postprandial periumbilical pain, and isolated spontaneous dissection of the superior mesenteric artery with mural thrombus was detected by abdominal computed tomography with contrast enhancement. By the percutaneous implantation of vascular metallic stent via femoral artery, he was treated successfully. We report a case of isolated spontaneous dissection of the SMA treated by a percutaneous endovascular stent replacement with a review of literature.
孤立性肠系膜上动脉（SMA）自发夹层而无主动脉夹层是急性肠系膜缺血的罕见原因。肠道血流突然减少可导致致命并发症，如缺血性坏死、休克和死亡。因此，在肠道梗死发生前进行早期诊断和治疗是决定患者预后的最重要因素。一名52岁男性出现餐后脐周疼痛，经腹部增强计算机断层扫描检测出孤立性肠系膜上动脉自发夹层并伴有壁内血栓形成。通过经股动脉经皮植入血管金属支架，他得到了成功治疗。我们报告一例经皮血管内支架置换治疗孤立性肠系膜上动脉自发夹层的病例并复习相关文献。
