ObjectivesCerebral venous sinus stenting (VSS) has emerged as a new surgical procedure for the treatment of severe idiopathic intracranial hypertension (IIH), and its popularity has been anecdotally on the rise.

Abstract
ObjectivesCerebral venous sinus stenting (VSS) has emerged as a new surgical procedure for the treatment of severe idiopathic intracranial hypertension (IIH), and its popularity has been anecdotally on the rise. This study explores recent temporal trends of VSS and other surgical IIH treatments in the United States.MethodsAdult patients with IIH were identified from the 2016-2020 National Inpatient Sample databases, and surgical procedures and hospital characteristics were recorded. Temporal trends of procedure numbers for VSS, CSF shunts, and optic nerve sheath fenestrations (ONSFs) were assessed and compared.ResultsA total of 46,065 (95% CI 44,710-47,420) patients with IIH were identified, of whom 7,535 patients (95% CI 6,982-8,088) received surgical IIH treatments. VSS procedures increased 80% (150 [95% CI 55-245] to 270 [95% CI 162-378] per year, p < 0.001). Concurrently, the number of CSF shunts decreased by 19% (1,365 [95% CI 1,126-1,604] to 1,105 [95% CI 900-1,310] per year, p < 0.001), and ONSF procedures decreased by 54% (65 [95% CI 20-110] to 30 [95% CI 6-54] per year, p < 0.001).DiscussionPractice patterns for surgical IIH treatment in the United States are rapidly evolving, and VSS is becoming increasingly common.
