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.

| Measure | Description | Time Frame |
|---|---|---|
| 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 | 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. | 12 months post-procedure |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | 12 months post-procedure |
| Recurrence |
