To present our experience of the clinical management of spontaneous isolated dissection of superior mesenteric artery (SIDSMA) and analyse the clinical features, imaging findings, and treatment outcomes.
In this retrospective study, eight consecutive patients with symptomatic SIDSMA were treated in Chang Gung Memorial Hospital between April 2007 and April 2010; among these patients, six underwent endovascular stent placement. The clinical manifestations, imaging findings, endovascular stent placement outcome, and follow-up results of the patients were retrospectively analysed.
Eight patients were diagnosed with SIDSMA by contrast-enhanced computer tomography. One patient died due to comorbidity before angiography. Six patients underwent percutaneous endovascular stent placement in the superior mesenteric artery (SMA): four patients with bare stents and two with stent grafts. Because it was not appropriate to perform stent implantation in the remaining patient, he received only conservative treatment. All seven patients had an uneventful recovery and the follow-up period was 16 month, ranging from 1 to 35 months.
For patients with symptomatic SIDSMA, endovascular repair is a feasible treatment choice with a high success rate and good clinical outcome.
介绍我们在治疗自发性孤立性肠系膜上动脉夹层（SIDSMA）方面的临床经验，并分析其临床特征、影像学表现和治疗结果。
本回顾性研究纳入 2007 年 4 月至 2010 年 4 月期间在长庚纪念医院接受治疗的 8 例有症状性 SIDSMA 患者，其中 6 例行腔内支架置入术。回顾性分析患者的临床表现、影像学表现、腔内支架置入术结果和随访结果。
8 例患者经增强计算机断层扫描诊断为 SIDSMA。1 例患者因合并症在血管造影前死亡。6 例患者在肠系膜上动脉（SMA）行经皮腔内血管支架置入术：4 例使用裸支架，2 例使用支架移植物。由于另 1 例患者不适合进行支架植入，故仅接受保守治疗。所有 7 例患者均恢复顺利，随访时间为 16 个月，1~35 个月不等。
对于有症状性 SIDSMA 的患者，血管内修复是一种可行的治疗选择，成功率高，临床效果好。
