Objectives: The clinical outcomes, safety, and efficacy of endovascular management are explored for symptomatic isolated superior mesenteric artery dissection (ISMAD). Methods: In this retrospective study, 51 consecutive patients with symptomatic ISMAD received endovascular management from three institutions between January 2011 and December 2019.These patients were categorized into group A (endovascular treatment was used as the first-line therapy) and group B(endovascular treatment was used as the second-line therapy). The general epidemiological data, clinical manifestations, first-episode symptoms, treatment process, imaging findings, follow-up outcomes were analyzed from the medical records. Results: A total of 51 patients with endovascular management were collected in this study. Significant differences were observed between the two groups with respect to the course (150 h vs. 57 h; p < 0.001), intestinal ischemia (26.32% vs. 6,25%; p = 0.04) and dissection length (45.26 ± 13.78 mm vs. 63.37 ± 12.73 mm; p < 0.001). Technical success rate was 90.2% (46/51). There was significant difference in the MOD (42.27 ± 23.41 min vs. 76.63 ± 28.62 min p < 0.001), MPSRT (4.67 ± 2.65 h vs. 7.32 ± 2.49 h, p = 0.02), LOS (9.52 ± 3.72 days vs. 11.86 ± 4.13 days; p = 0.01) between the two groups. The bleeding complication rate was 7.84% (one patient in group A and three patients in group B). A total of 48 (94.12%, 48/51) patients were followed up for a median of 36.51 months (range, 4–87 months). Positive events of the SMA were achieved in 81.25% (39/48), and negative events of the SMA were achieved in 18.75% (8/48) based on the follow-up contrast-enhanced CT scan. Conclusions: Endovascular management of symptomatic ISMAD has a high technical success rate and efficient at controlling symptoms. Furthermore, as more positive events occur, endovascular management should be encouraged early when pain persists after conservative management or there are signs of disease progression.
