RESUMO
OBJECTIVE: To review the literature of venous sinus stenosis (VSS) treatment in children for idiopathic intracranial hypertension (IIH) and present our own institutional case. METHODS: A literature review was conducted using the PubMed and MEDLINE databases up to June 2020. From 134 studies that were screened, 6 studies were chosen for analysis that included patients <18 years old, a diagnosis of IIH that fit Dandy diagnostic criteria, and angiogram obtained to assess for VSS. IIH symptoms experienced in the pediatric population and efficacy of venous sinus stenting were analyzed. RESULTS: Eleven patients identified in the literature and 1 patient from our institution were included in the analysis. There was no statistically significant difference in pressure gradient response to stenting between male and female patients (P = 0.424) or patients with body mass index >90th percentile (P = 0.626). Larger decreases in pressure gradient after stent placement correlated with headache resolution (P = 0.0005). Patients who underwent unilateral stenting showed greater reduction in pressure gradient compared with patients who underwent bilateral stenting (average change 24 mm Hg vs. 5.75 mm Hg, P = 0.003). CONCLUSIONS: Our analysis showed that VSS treatment has the potential to be a safe option for IIH in pediatric patients. VSS treatment has shown similar results to traditional cerebrospinal fluid diversion procedures, with a lower complication rate and need for revision. More studies should be conducted to analyze the long-term efficacy and safety of VSS treatment in pediatric patients with IIH.
