Endovascular Treatment of Idiopathic Intracranial Hypertension Secondary to Venous Stenosis

Abstract

Introduction Idiopathic intracranial hypertension (IIH) is a condition characterized by signs and symptoms of elevated intracranial pressure (ICP). Although the role of venous sinus stenosis in the pathophysiology of IIH is controversial, venous angioplasty with stenting has been proven to decrease cerebral venous pressure and intracranial pressure. This study aims to identify and quantify the clinical improvement obtained by patients with IIH, refractory to prior pharmacological treatment, undergoing endovascular venous angioplasty in a neuroendovascular reference service.
