Abstrakt:	Background: Mechanical thrombectomy (MT) is the standard treatment for acute large vessel occlusion (LVO). Recurrent LVO can still occur in patients who already underwent MT for the first LVO. This study aimed to evaluate the efficacy of repeating MT for recurrent LVO. Methods: This meta-analysis of the available literature was conducted to summarize the current evidence regarding repeated MT outcomes in patients with recurrent LVO. All studies with ≥ 1 outcomes of interest were included. The Newcastle-Ottawa Scale (NOS) was used for risk of bias assessment. Results: Twenty studies, 10 observational (n = 21,251 patients) and 10 case reports (n = 10 patients), were included. 266 patients (62.78% females) with recurrent LVO were identified, with an overall prevalence of 1.6% and a mean age of 65.67 ± 16.23 years. Cardio-embolism was the most common mechanism in both times, with a median of 15 days between the first and second LVOs. Compared with pre-intervention, the first and second MTs significantly reduced the National Institute of Health Stroke Scale (NIHSS) score, (mean difference (MD) = -8.91) and (MD = -5.97) respectively, with a significant difference (p = 0.001). The rate of favorable outcome (modified Rankin scale (mRS) score 0-3) was 82.6% and 59.2% after the first and second MTs respectively, with a significant difference (p < 0.001). Conclusion: In properly selected recurrent LVO patients, repeated MT is efficacious and safe. A prior MT procedure should not discourage aggressive treatment as many patients may achieve favorable outcomes.
