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. Methods A retrospective analytical study of 25 cases of IIH with transverse sinus stenosis operated on in a reference service using the endovascular method, in which clinical data from medical records and information about the procedure were analyzed. Results Of the 25 patients, 22 were women, and the mean age was 42 years. All patients were refractory to prior clinical treatment. At the clinical presentation, all had headaches. There were no complications or failures from the procedures performed. In the 30-day evaluation, there was a significant decrease in all the symptoms reported. Conclusion Venous sinus stenting is safe and effective in patients with IIH with transverse sinus stenosis refractory to clinical treatment, with substantial symptomatic improvement and good evolution in the postoperative follow-up period.
