PURPOSE: This study aimed to investigate the factors influencing favourable clinical outcomes in idiopathic intracranial hypertension (IIH) patients with venous sinus stenosis (VSS) who received stenting treatment.
METHODS: In this prospective cohort study, we analyzed a total of 172 IIH patients with VSS treated with venous sinus stenting. Clinical outcomes were categorized as either "complete resolved" or "improved". We employed multivariable logistic regression modeling to identify independent factors associated with the clinical outcomes. The predictive accuracy of the model was assessed using receiver operating characteristic (ROC) analysis.
RESULTS: Out of the total cohort, 126 patients exhibited asymptomatic clinical outcomes, while 46 patients showed improved clinical outcomes. Patients with asymptomatic clinical outcomes demonstrated notably lower preoperative BMI (26.8 kg/m2 versus 28.7 kg/m2, P = 0.013). In multivariate analysis, preoperative BMI (odds ratio [OR] = 1.108, 95% confidence interval [CI] = 1.009-1.216) was an independent factor of complete resolution of the symptoms. In the receiver operating characteristic (ROC) analysis, the identified cut-off BMI for the highest sensitivity (0.5) and specificity (0.754) was determined to be 29.3 kg/m2.
CONCLUSION: Lower BMI may be associated with the complete resolution of symptoms in IIH patients with VSS who received venous sinus stenting treatment.
