Isolated spontaneous dissection of the superior mesenteric artery is the most common digestive artery dissection. It is a rare cause of acute abdomen. Only a few hundred cases have been reported in the literature.
We report a 40-year-old man with a past medical history of high blood pressure who presented abdominal pain that was related to a spontaneous dissection of the superior mesenteric artery. Computed tomography revealed an isolated dissection of superior mesenteric artery. There were no evidence of bowel ischemia. We decided a conservative treatment and the outcome was favorable, without recurrent symptoms or disease progression.
Based on this case report, we discuss the etiology of this vascular lesion and the contribution of computed tomography in the diagnosis, the therapeutic strategy and the follow-up of spontaneous dissection of superior mesenteric artery.
孤立性肠系膜上动脉自发性夹层是最常见的消化动脉夹层。它是急性腹痛的罕见病因。文献中仅报道了数百例。
我们报告一名40岁男性，既往有高血压病史，出现与肠系膜上动脉自发性夹层相关的腹痛。计算机断层扫描显示孤立性肠系膜上动脉夹层。没有肠缺血的证据。我们决定采取保守治疗，结果良好，无复发症状或疾病进展。
基于本病例报告，我们讨论了这种血管病变的病因以及计算机断层扫描在肠系膜上动脉自发性夹层的诊断、治疗策略和随访中的作用。
