Traumatic arteriovenous fistula associated to pseudoaneurysm of the superficial temporal artery in a child - Case report and literature review Fístula arteriovenosa traumática associada a pseudoaneurisma da artéria temporal superficial em uma criança - Relato de caso e revisão da literatura

The arteriovenous fistulae (AVFs) and the extracranial traumatic pseudoaneurysms are uncommon malformations and in the majority of the cases are associated to closed head trauma with high intensity blunt lesion. The diagnosis is generally clinical, though the exam of choice for definitive diagnosis is an angiography. In minor lesion cases it’s possible to successfully approach it with endovas cular embolization. The surgical excision though, is the method of choice for the treatment. Here is reported a case of a 9-year-old male patient, diagnosed with AVF involving the frontal branch of the superficial temporal artery, secondary to blunt head trauma occurred three years before diagnosis.
