摘要

Background

Randomized controlled trials have demonstrated the efficacy and safety of endovascular thrombectomy (EVT) in patients with acute large vessel occlusion stroke. However, its long-term benefits remain uncertain. Therefore, this study aimed to investigate the long-term clinical outcomes of EVT.

Methods

We searched PubMed, Embase, Cochrane Library, and Web of Science databases to identify relevant literature pertaining to patients with acute ischemic stroke who were treated with EVT plus medical management (MM) compared with MM alone, until August, 31, 2024. The primary outcome was functional independence (defined as a score of 0 to 2 on the modified Rankin scale [mRS]) at 12 months or beyond, while the safety outcome was mortality at 12 months or longer. Effect sizes were computed as risk ratio (RR) with random-effect or fixed-effect models. This study was registered on the International Prospective Register of Systematic Reviews on June 15, 2024 (PROSPERO, CRD42024554043).

Results

A total of 4546 articles were obtained through the search. After excluding those that did not meet the inclusion criteria, 9 randomized controlled trials with 3358 patients (1821 and 1537 assigned to EVT + MM and MM alone group, respectively) were included in this analysis. The EVT + MM group had a higher proportion of functional independence (32.9% vs 18.2%, risk ratio 2.07, 95% confidence interval 1.50–2.87, P < 0.001) and lower mortality (34.1% vs 39.7%, risk ratio 0.86, 95% confidence interval 0.78–0.94, P = 0.001) compared to the MM group.

Conclusion

Endovascular thrombectomy was associated with improved functional outcomes and reduced mortality in acute large vessel occlusion stroke patients and presented a long-term favorable effect.
