A 10-year-old, male patient with a head injury caused by a fall presented with chemosis, exophthalmos, right orbital bruit, and intracranial venous reflux, based on which posttraumatic carotid cavernous fistula (CCF) was diagnosed. Coil embolization was semi-urgently performed for the dangerous venous drainage. After the treatment, right abducens nerve palsy newly appeared. To treat the neurological symptoms and preserve the parent artery, curative endovascular treatment using a pipeline embolization device (PED) with coil embolization was performed after starting dual antiplatelet therapy (DAPT). The CCF and abducens nerve palsy finally resolved, and the internal carotid artery (ICA) was remodeled. Use of the PED with adjunctive coil embolization was effective and safe in the present case of pediatric traumatic direct CCF.
