  "abstract": "Background Venous sinus stenting (VSS) is an increasingly performed procedure for the treatment of idiopathic intracranial hypertension (IIH) refractory to medical treatment. VSS is typically performed under general anesthesia.Objective To present our experience of VSS in patients with IIH performed under conscious sedation.Methods Retrospective review of a prospectively maintained database of all patients with IIH who underwent VSS in a single center between September 2019 and January 2024. The sedation protocol consisted of a remifentanil-based target-controlled infusion. Patients’ clinical and radiological data, dosage of anesthesia, procedural characteristics, and outcomes were collected.Results Twenty-six patients with IIH underwent venous manometry (VM) and VSS under awake sedation and were included in our study. Patients were predominantly women (24/26) with a median age (IQR) of 33 (13) years. The median (IQR) body mass index was 34 (10) kg/m 2. There was no need for general anesthesia conversion. Technical success was achieved in all patients. Median (IQR) follow-up after stenting was 7 (2) months. All patients reported resolution of the pulsatile tinnitus; headaches regressed in 20/24 (83.3%) patients and papilledema improved in 16/20 (80%). Only one non-neurological complication (retroperitoneal hematoma) occurred, without any permanent morbidity or mortality.Conclusion Our study confirms that performing VM and VSS under conscious sedation is safe and feasible. Conscious sedation is a viable alternative to general anesthesia for managing IIH in these patients.",
