Early and Mid-Term Outcomes of Endovascular Treatment for Symptomatic Spontaneous Isolated Superior Mesenteric Artery Dissection: A Retrospective Single-Center Study

< .001). The rate of adverse events and early re-intervention was 6.5% (6/93) and 5.4% (5/93). The median follow-up time was 27 months (range 6-64), and there was 1 case of late re-intervention, 1 case of stent occlusion, and no dissection-related deaths. Endovascular treatment showed a satisfactory outcome in treating symptomatic SISMAD, with a good cumulative complete remodeling rate.
