This study aims to evaluate the prognosis in patients with spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) who have been treated with stents.
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 1 years after patients have received stents.

Patency of stents deployed in the superior mesenteric artery
The patency of stents deployed in the superior mesenteric artery shall be evaluated via computed tomographic angiography
Time frame: 12 months post-procedure
Remodeling of the superior mesenteric artery
Complete remodeling was defined as the absence of residual arterial dissection and stenosis via follow-up computed tomographic angiography. Incomplete remodeling was defined as improved luminal patency of the superior mesenteric artery but worse than complete remodeling.
Time frame: 12 months post-procedure
Relief of symptoms
Most of patients with SIDSMA are symptomatic. The symptoms mainly include abdominal pain, hematochezia, nausea and vomiting.After the procedure, the time delay between the stent implantation and disappearance of these symptoms are documented.
Time frame: 12 months post-procedure
Recurrence
New dissection in the superior mesenteric artery
Time frame: 12 months post-procedure
