[Advances in the classification and treatment of isolated superior mesenteric artery dissection].

Isolated superior mesenteric artery dissection (ISMAD) has attracted more and more clinicians' attention in recent years. Patients onset of ISMAD often present with abdominal pain. The misdiagnosis or miss diagnosis is common because of the non-specific symptoms and signs, which even can endanger lives in serious cases. Imaging classification is of great significance for diagnosis and treatment of ISMAD. The Sakamoto classification and the Yun classification are two classical classified methods. However, with the further study of ISMAD, various new classifications emerge. Conservative treatment was once considered as the preferred. As the rapid development of endovascular therapy and the great progress of new devices, stenting therapy can significantly improve symptoms and achieve satisfactory long-term effects, and be even expected to become the preferred method for clinical therapy of ISMAD. However, the long-term effects of endovascular therapy still need a large number of follow-up data, and complications after stent implantation can't be ignored.近年来，孤立性肠系膜上动脉夹层被越来越多的临床医师关注。患者发病时常表现为腹痛，其症状、体征无特异性，易被误诊、漏诊，严重时可危及患者生命。影像学分型对该疾病的诊断和指导治疗有着重要意义，Sakamoto分型和Yun分型是两种经典的分型方式。随着对该病了解的不断深入，各种新分型不断出现，各有千秋。保守治疗曾被认为是孤立性肠系膜上动脉夹层的首选治疗方式，但随着血管腔内治疗的迅速发展和新器械的不断出现，支架成形术后患者症状改善明显，中长期效果满意，有望成为该疾病的首选治疗方法。然而，腔内治疗的远期效果仍需大样本随访资料支持，支架植入后并发症同样不可忽视。.
