Introduction: Extracranial carotid artery pseudoaneurysm is a rare complication of deep neck space infection, and no evidence-based treatment guidelines are available in the literature. Method: To clarify the existing experience of the different treatment strategies, the authors performed a systematic literature search using the PubMed, Ovid EMBASE, and Scopus databases in accordance with PRISMA guidelines to review all reported cases of pediatric patients with infectious carotid pseudoaneurysms larger than 1 cm. Results: Twenty-six patients with a median age of 4 years (range 6 months–15 years) were identified. Eighteen patients (69.2%) were treated with endovascular methods, 6 patients (23.1%) with surgical methods, 1 patient (3.8%) with a hybrid endovascular/surgical approach, and 1 patient (3.8%) with conservative management. Recurrence of the pseudoaneurysm occurred in 2 cases (7.7%), both of which were successfully retreated. Of the 6 patients (23.1%) who presented with pre-procedure neurologic deficits, 3 patients had complete or near complete resolution of symptoms after intervention and 3 patients had persistent deficits at last follow-up. Four patients (15.4%) experienced new neurologic deficits post-procedure that resolved at last follow-up. Conclusion: The endovascular treatment tends to be the preferred option to treat a large or giant infectious pseudoaneurysm of the carotid artery in the pediatric patient. However, more evidence is necessary to elucidate comparative safety and efficacy profiles of endovascular and surgical management strategies.
