Angioembolization as a life-saving maneuver for unstable pelvic fractures in skeletally immature children: a multicenter case series.
Article in Frontiers in pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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: Hemodynamically unstable pelvic fractures (HUPF) in skeletally immature children and adolescents carry significant mortality. While internal iliac artery embolization (IIAE) is a cornerstone of management for HUPF in adults, data on its application and outcomes in this truly pediatric population, particularly in China, are scarce. This study aimed to evaluate the feasibility, safety, and clinical outcomes of IIAE for HUPF in this specific, vulnerable group. Methods: This multicenter, retrospective case series included patients aged 15 years or younger who presented with HUPF and underwent IIAE at three major Chinese trauma centers between 2019 and 2023. Key outcomes included immediate hemorrhage control, in-hospital mortality, and long-term complications. Results: A total of seven patients underwent IIAE. The cohort demonstrated severe trauma, with a median Pelvic Abbreviated Injury Scale (AIS) of 5 and a median Injury Severity Score (ISS) of 36. Of the six patients who underwent contrast-enhanced computed tomography (CECT), active arterial extravasation was identified in four. However, subsequent angiography confirmed life-threatening arterial injuries in all seven patients, including the two with negative CECT scans. Immediate and sustained hemodynamic stability was achieved in six patients (85.7%). The single mortality occurred in a patient with refractory hemorrhagic shock who required a massive transfusion of 28.5 units of red blood cells, whereas the median for the six survivors was 4 units. At a median follow-up of 22 months, all survivors were ambulatory and no major procedure-related ischemic complications were observed. Conclusion: IIAE is a feasible and effective life-saving intervention for HUPF in skeletally immature patients. A negative CECT scan does not rule out significant arterial injury, underscoring the vital role of prompt angiography. We recommend a low threshold for early intervention, with consideration of non-selective embolization as a primary damage control tactic in these critically injured children.
