Background

Mechanical thrombectomy is the standard of care for acute ischemic stroke due to large vessel occlusions.

Methods

A systematic search of PubMed, Cochrane, Embase, and ClinicalTrials.gov was conducted in line with PRISMA guidelines.

n = 476 patients

Results

tigertriever patients were more likely to achieve successful reperfusion than self-expanding stent retrievers

OR 1.74 (95% CI 1.07 to 2.83)

CI excludes the null - significant

More results

Target intracranial vessel occlusion locations were internal carotid artery (internal carotid artery), middle cerebral artery (middle cerebral artery) M1, middle cerebral artery M2 and basilar artery.

27.4%; OR 0.72 (0.44-1.16); p = 0.17; I 2 = 0%].

More results

Rates of sICH within 24 h, functional independence at 90 days and mortality at 90 days were similar.

The overall risk of bias was low to moderate.

Conclusion · 1 of 2

In this exploratory meta-analysis of retrospective cohorts, Tigertriever was associated with significantly higher reperfusion rates, while safety and functional outcomes appeared comparable between groups.

Conclusion · 2 of 2

Findings should be interpreted cautiously given study-level heterogeneity, limited sample size, inconsistent procedural reporting, and the observational nature of included studies.
