Introduction Venous Sinus Stenting (VSS) is safe, improves symptoms and reduces Intracranial Pressure (ICP) in patients with Idiopathic Intracranial Hypertension (IIH) when conservative measures are inadequate (Azzam et al., 2024). VSS results in reduced headache, visual symptoms and healthcare utilization rate and supports decreased rates of cerebrospinal fluid (CSF) diversion through Ventriculoperitoneal (VP) shunting (Intrapiromkul et al., 2025). In this study we describe a single‐center experience of devices and techniques used and discuss outcomes at follow up. Methods We retrospectively reviewed patients who underwent VSS for IIH at a single center from May 2023 to June 2025 who demonstrated a trans‐stenosis gradient of greater than 8 and gathered information on demographics, symptoms, devices/techniques used and outcomes as measured by headache and papilledema. Results Overall 15 female patients with a mean age of 33 were included with median follow up at 31 days. Headache was the most common symptom reported at the time of presentation. Median opening pressure was 39.5 cm H2O although 3 cases did not report it. The median trans‐stenosis gradient was 20 mmHg prior to stenting. Results as noted in Figure 1. Headache improvement was noted in 9/15 cases, 5 reported no improvement and no follow up was noted in 1 case. Papilledema improved in 10/15 patients, 1 patient had no improvement and data is missing in 4 cases. 8 French catheters were used in 10 cases and 3 cases used 6 French catheters. Base camp guide catheter used in 11 cases. HiPoint support catheter was used in 10 cases followed by Tenzing 8 catheters in 9 cases. Conclusions Our results show that VSS is safe and effective in reducing ICP as evidenced by reduction in papilledema, and the type of catheter used was not associated with outcomes. No patients in our analysis needed VP shunt placement for CSF diversion. Improvement of headache was reported in more than half cases and some patients needed adjunct pharmacotherapy.
