Temporary flow arrest using EMBOGUARD™ balloon guide catheter may improve functional outcomes in acute stroke thrombectomy: a multicenter retrospective study.
Observational study in Frontiers in neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Balloon guide catheters (BGCs) have demonstrated benefits in mechanical thrombectomy (MT) for acute ischemic stroke (AIS), including improved recanalization rates and reduced distal embolization. The EMBOGUARD™ balloon guide catheter (Johnson & Johnson Neurovascular, Irvine, CA) represents a novel design with enhanced flexibility and compatibility with large-bore aspiration catheters. This study aims to evaluate the safety and efficacy of the EMBOGUARD™ BGC compared with non-BGC approaches. Methods: We conducted a retrospective multicenter study to analyze patients with AIS due to anterior large vessel occlusions (LVOs) who underwent MT between January 2022 and December 2024. Patients were divided into two groups: those treated with t☺he EMBOGUARD™ BGC and those treated without BGC. Primary outcomes included first-pass effect (FPE), successful recanalization (mTICI ≥2b), procedural time, number of passes, and distal embolization. Secondary outcomes included 90-day functional outcome (modified Rankin Scale [mRS] 0-2), mortality, and symptomatic intracranial hemorrhage (sICH). Results: A total of 178 patients were included (EMBOGUARD: Conclusion: The EMBOGUARD™ balloon guide catheter demonstrated comparable technical efficacy with reduced procedural times and improved clinical outcomes compared with non-BGC techniques in endovascular thrombectomy for acute ischemic stroke. These findings support the use of EMBOGUARD™ as a reasonable tool for flow arrest in stroke intervention.
