- W3184979291 abstract "<h3>Introduction/Purpose</h3> Patterns in utilization and characteristics of endovascular venous stenting (EVS) for Idiopathic Intracranial Hypertension (IIH) are unknown. We aimed to explore the frequency and characteristics of EVS for IIH in the United States, and to compare with admissions undergoing Optic nerve sheath fenestration (ONF) or Shunting. <h3>Materials and Methods</h3> In this retrospective longitudinal cross-sectional analysis, hospitalizations with a diagnosis of IIH were identified in the National Inpatient Sample (2010-2017), excluding venous thrombosis and other causes of intracranial hypertension. Temporal trends in utilization of EVS, ONF, and shunt procedures were explored. Logistic regression was used to measure differences according to age, race, sex, and other patient and hospital-level characteristics. <h3>Results</h3> Between 2010 and 2017, 784 EVS, 352 ONF and 11803 shunting procedures were identified for the treatment of IIH. Among those undergoing EVS, median age was 32 (IQR 28-40), 93.1% were women, and 73.5% of EVS procedures were elective admissions. Total IIH-related hospitalizations increased from 11350 in 2010 to 24684 in 2017. Patient age, sex or race were not associated with EVS use, but urban-teaching hospital setting, and larger hospital size were independently associated with EVS utilization. EVS increased significantly and continuously from 2010 to 2017 (p for trend <0.001) whereas shunting and ONF use remained stable (<b>Abstract 24 figure 1</b>). Length of hospital stay was considerably lower following EVS (median 1, IQR 1-2) as compared to ONF (median 4, IQR 2-7) and shunting procedures (median 2, IQR 1-4) (p<0.01). <h3>Conclusion</h3> This study presents novel population-level data on national trends in the frequency and characteristics of venous stenting in IIH. EVS was associated with shortest length of hospital stay. A continuous increase in venous stenting with a relative stable use of shunting and ONF suggests an increasing role for endovascular therapies in IIH. <h3>Disclosures</h3> <b>H.
