Successful transarterial embolization of a neonatal tongue vascular malformation presenting with life-threatening airway compromise: a case report
摘要
Vascular 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 presentationWe 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 outcomeSuperselective 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.
