Early middle meningeal artery embolization for small acute epidural hematomas: a clinical study from a single center.

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
Objective: Small acute epidural hematomas (EDHs) are generally managed conservatively; however, in certain instances, they may necessitate surgical evacuation owing to delayed hematoma expansion. This study aims to evaluate whether early embolization of the middle meningeal artery (MMA) can prevent hematoma progression in patients with small acute epidural hematomas accompanied by skull fractures involving meningovascular structures. We hypothesize that early MMA embolization could be a prophylactic strategy to prevent hematoma progression. Methods: A retrospective study was conducted on 14 patients with small EDHs (volume <30 mL) and skull fractures intersecting MMA branches, who were treated via endovascular embolization at our center from October 2021 to August 2024. Onyx Results: Preoperative computerized tomography (CT) scans confirmed skull fractures at EDH sites, and preoperative angiography showed vascular lesions of the MMA (including active contrast leak or pseudoaneurysm) in all cases. All patients underwent the procedure under local anesthesia and obtained an MMA occlusion successfully, which was confirmed by subsequent angiography. All patients showed no hematoma expansion on follow-up CT scans and avoided craniotomy. All patients were discharged without neurological deficits. Conclusion: This series establishes MMA embolization as a prophylactic approach for small acute EDHs with skull fractures intersecting MMA branches. Early super-selective angiography is crucial for detecting vascular injuries, and subsequent embolization guided by intraoperative findings may reduce monitoring burden and the risk of delayed expansion in selected patients.
