Microcatheter delivery of embolic protection devices for acute atherosclerotic tandem occlusion: patient series.
Article in Journal of neurosurgery. Case lessons, 2025. 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
backgroundAcute atherosclerotic tandem occlusions of the internal carotid artery (ICA) present significant technical challenges for endovascular intervention. Optimal strategies for the efficient and safe deployment of embolic protection devices (EPDs) in this context remain to be established, as conventional approaches often necessitate multiple device exchanges, prolonging procedural time and potentially increasing risk. OBSERVATIONS: In this retrospective series, 16 consecutive patients with acute ischemic stroke due to ICA occlusion underwent endovascular therapy utilizing a microcatheter-facilitated EPD (MICRO-EPD) delivery technique. This novel approach, leveraging a 0.027-inch microcatheter for direct EPD deployment, eliminated the need for standard exchange maneuvers and reduced procedural complexity. Technical success was achieved in all cases, with a median puncture-to-recanalization time of 55 minutes. At 90 days, 56.3% of patients achieved favorable functional outcomes (modified Rankin Scale score ≤ 2). Symptomatic intracranial hemorrhage and mortality each occurred in 1 patient (6.3%). No device-related technical failures or unanticipated complications were observed. LESSONS: The MICRO-EPD technique demonstrates a promising advance in the management of acute atherosclerotic tandem occlusions, offering a simplified, safe, and effective method for EPD deployment. This strategy has the potential to optimize procedural efficiency and improve patient outcomes, meriting further prospective evaluation in broader clinical settings. https://thejns.org/doi/10.3171/CASE25622.
