Xu L, Shao J, Zhang D, et al. - Researchers performed this study among symptomatic patients with spontaneous isolated superior mesenteric artery dissection (SISMAD), to compare the results of conservative and endovascular treatments in this patient population. Enrolled patients were 42 in total, and were recruited from a single center. On the basis of symptoms, conservative treatment and endovascular treatment was given to 15 and 27 patients, respectively. In the conservative group and in the endovascular group, the rates of symptom relief were estimated to be 93.3% and 96.3%, respectively. Statistically significantly longer symptom-free survival was observed in the endovascular group vs the conservative group. Overall, findings revealed a lower rate of symptom recurrence as well as a higher rate of superior mesenteric artery remodeling in the long term in patients who received endovascular treatment for symptomatic SISMAD.
