Abstract

Objective: Chronic mesenteric ischaemia (CMI) treatment focuses on symptom relief and prevention of disease progression. Endovascular repair represents the main treatment modality, while data on the associated antiplatelet regimen are scarce. The aim of this meta-analysis was to assess the early and midterm outcomes of endovascular repair in patients with CMI. Data sources: Randomised controlled trials and observational studies (1990 – 2022) reporting on early and midterm endovascular repair outcomes in patients with atherosclerotic CMI. Review Methods: The PRISMA guidelines and PICO model were followed. The protocol was registered to PROSPERO (CRD42023401685). Medline, Embase (via Ovid), and Cochrane databases were searched (end date 21 February 2023). The Newcastle–Ottawa Scale was used for risk of bias assessment, and GRADE for evidence quality assessment. Primary outcomes were technical success, 30 day mortality, and symptom relief, assessed using prevalence meta-analysis. The role of dual antiplatelet therapy (DAPT) was investigated using meta-regression analysis. Results: Sixteen retrospective studies (1 224 patients; mean age 69.8 ± 10.6 years; 60.3% female) reporting on 1 368 target vessels (57.8% superior mesenteric arteries) were included. Technical success was 95.0% (95% CI 93 – 97%, p = .28, I2 19%, low certainty), the 30 day mortality rate was 2.0% (95% CI 2 – 4%, p = .93, I2 36%, low certainty), and immediate symptom relief was 87.0% (95% CI 80 – 92%, p < .010, I2 85%, very low certainty). At mean follow up of 28 months, the mortality rate was 15.0% (95% CI 9 – 25%, p = .010, I2 86%, very low certainty), symptom recurrence 25.0% (95% CI 21 – 31%, p < .010, I2 68%, very low certainty) and re-intervention rate 26.0% (95% CI 17 – 37%, p < .010, I2 92%, very low certainty). Single antiplatelet therapy (SAPT) and DAPT performed similarly in the investigated outcomes. Conclusion: Endovascular repair for CMI appears to be safe as first line treatment, with a low peri-operative mortality rate and acceptable immediate symptom relief. During midterm follow up, symptom recurrence and need for re-intervention are not uncommon. SAPT appears to be equal to DAPT in post-operative outcomes.
