Background:
The EmboTrap Recanalization Device is a novel stent retriever for thrombectomy in the setting of acute ischemic stroke due to large-vessel occlusion.
Purpose:
Our aim was to summarize the safety and efficacy of the EmboTrap Recanalization Device in acute ischemic stroke-large-vessel occlusion through a systematic review and meta-analysis.
Data Sources:
Medline, EMBASE, the Cochrane Library, Web of Science, and Google Scholar were searched up to April 2022.
Study Selection:
Nine observational studies using the EmboTrap Recanalization Device were selected.
Data Analysis:
We adapted effect size with 95% CIs for dichotomous data. P value <.05 was statistically significant.
Data Synthesis:
The estimated rate of successful recanalization (modified TICI 2b-3) was 90% (95% CI, 86%-95%; I = 82.4%); 90-day favorable outcome (mRS 0-2), 53% (95% CI, 42%-63%; I = 88.6%); modified first-pass effect, 43% (95% CI, 35%-51%; I = 63.7%); and first-pass effect, 36% (95% CI, 29%-46%; I = 10.7%). The rate of any intracerebral hemorrhage was 19% (95% CI, 16%-22%; I = 0.0%); symptomatic intracerebral hemorrhage, 5% (95% CI, 1%-8%; I = 84.6%); and 90-day mortality, 14% (95% CI, 9%-19%; I = 79.3%). Subgroup analysis showed higher rates of complete recanalization for EmboTrap II than for the EmboTrap System.
Limitations:
The included studies are single-arm without direct comparison with other stent retrievers. Some of the studies recruited had a small sample size and were limited by the retrospective study design. In addition, the uncertain heterogeneity among studies was high.
Conclusions:
The EmboTrap Recanalization Device is safe and efficient in treating acute ischemic stroke due to large-vessel occlusion.
