- W4367018560 abstract "Introduction Venous sinus stenosis (VSS) stenting in medically refractory Idiopathic Intracranial Hypertension (IIH) patients has emerged as an effective treatment with low rates of failure and recurrence. However, the best treatment strategy following recurrence of symptoms in previously stented patients with initial response is unclear and frequently leads to shunt placement. We investigated the role of re‐stenting in patients with recurrence after prior successful stenting. Methods This is a retrospective review of a prospectively maintained IIH registry. Inclusion criteria included patients with confirmed IIH and angiographically demonstrable VSS who underwent interventions from 2012–2022. Patients were divided into those who underwent a single stenting procedure (Group S) and those who underwent placement of an additional stent due to recurrence of clinical symptoms and angiographic stenosis (Group R). All re‐stenting was performed in adjacent or remote regions of stenosis. Bivariate analyses were utilized to compare clinical outcomes. Results 86 patients were included with a median age of 33 [IQR 26‐39] and 94% were females. Group S (79/86) and Group R (7/86) had similar baseline characteristics. There was similar improvement in post‐stenting opening pressure (22.4±6.7 vs. 25.2±4.6 cm H2O, p = 0.35, Group S vs. Group R), change in opening pressure (11.6±10.4 vs. 5.3±12.2 cm H2O, p = 0.20, Group S vs. Group R) and resolution of tinnitus (91.8 vs. 80%, p = 0.28, Group S vs. Group R). Headache improvement was higher in Group S at 6 weeks, but similar at 6 months (92.8 vs. 60%, p = 0.02 and 88.2 vs. 80%, p = 0.59, Group S vs. Group R). Group S also had higher improvement in visual disturbances at 6 months (93.8 vs. 60%, p = 0.01, Group S vs. Group R), but similar improvement in papilledema (92.2 vs 100%, p = 0.68, Group S vs. Group R). None of the re‐stented patients required VPS rescue. Conclusions VSS re‐stenting in IIH patients with recurrence after initial stenting is feasible with similar efficacy in reducing intracranial pressure and symptoms." @default.
