This study is a prospective, observational study. Patients who have been diagnosed as spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) and treated with stents are enrolled in the study. We will evaluate the patency of stent, remodeling of the dissection and the relief of the symptoms in the next 2 years after patients have received stents.
