Successful transarterial embolization of a neonatal tongue vascular malformation presenting with life-threatening airway compromise: a case report.
Article in CVIR endovascular, 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
backgroundVascular malformations of the tongue are rare congenital vascular anomalies that may present with bleeding, feeding difficulty, and life-threatening airway compromise in neonates. Prompt diagnosis and early intervention are essential because of the limited airway reserve in this age group. Magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) play important roles in lesion characterization and treatment planning. CASE PRESENTATION: We report the case of a 1-month-20-day-old infant weighing 3 kg who presented with progressive tongue swelling, intermittent bleeding, and respiratory distress requiring endotracheal intubation for airway stabilization. MRI demonstrated a vascular lesion involving the anterior tongue with multiple internal flow voids and homogeneous post-contrast enhancement. DSA revealed a hypervascular lesion supplied predominantly by branches of the lingual artery arising from the external carotid artery. INTERVENTION AND OUTCOME: Superselective transarterial embolization was successfully performed using a microcatheter system and 250 μm polyvinyl alcohol (PVA) particles. Post-embolization angiography demonstrated significant reduction in vascular blush with successful devascularization of the lesion. Clinically, the infant showed cessation of bleeding, improvement in airway patency, and no immediate procedural complications.
conclusionTransarterial embolization represents a safe and effective minimally invasive treatment option for neonatal tongue vascular malformations presenting with airway compromise. Careful technique and specialized neonatal endovascular expertise are essential to achieve favorable clinical outcomes while minimizing procedural complications.
