Abstract: Objective:To summarize the midterm to long-term outcomes and experiences of endovascular treatment (ET) of spontaneous isolated superior mesenteric artery dissection (SISMAD).Methods:The clinical data of 31 SISMAD patients from Jan 2011 to Dec 2019 treated with ET was retrospectively analyzed.Results:Successful ET was achieved in 29 patients with a technical success rate of 93.5%. A total of 36 self-expandable bare stents were planted in 28 patients and plain old balloon angioplastry (POBA) was performed in 1 patient. Abdominal pain disappeared within 24 hours in 89.3% of the patients after stenting. The rate of perioperative complication was 3.2%. There was no SMA dissection rupture bleeding, nor perioperative death occurred. The mean follow-up time was 53.5 (range, 6 to 110) months. There was no dissecting aneurysm formation, no SMA rupture and bleeding, and no stent rupture during the follow-up. The post ET 1-year, 3-year, and 5-year free from reintervention rate were 100%, 100%, and 91.7%, respectively.Conclusions:ET for SISMAD is safe and effective with satisfactory perioperative and midterm to long-term outcomes.
