Purpose: To evaluate the incidence of surgical intervention in pediatric intracranial hypertension (IH), evaluate the visual outcomes of surgically managed patients, and identify potential predictors for surgical intervention.
Methods: The medical records of patients with primary and secondary IH at Nationwide Children's Hospital from 2010 to 2017 were reviewed retrospectively. Presenting characteristics of medically and surgically managed patients were compared, and the clinical courses of surgically managed patients were reviewed.
Results: A total of 129 medically and 14 surgically managed patients were included. The surgical incidence was 9.8%. Final visual acuity in 27 of 28 surgically managed eyes was 20/25 or better. In combined primary and secondary IH patients, elevations in body mass index (BMI; OR = 1.06; 95% CI, 1.01-1.11; P = 0.022) and lumbar puncture opening pressures ≥52 cm H2O (OR = 6.17; 95% CI, 1.93-19.67; P = 0.002) were significantly associated with the likelihood of surgical intervention when assessed by univariate logistic regression; grade of papilledema >2 was of marginal significance. After controlling for BMI, a lumbar puncture opening pressure of ≥52 cm H2O was more likely to result in surgery (adjusted OR = 4.69; 95% CI = 1.39-15.98; P = 0.013).
Conclusions: Most pediatric IH can be treated medically. Patients with lumbar puncture opening pressures ≥52 cm H2O at the time of diagnosis are at a higher risk of surgical intervention and should be monitored closely. Elevations in presenting BMI and grade of papilledema may also increase the odds of surgery.
