Endovascular Intervention In A Chronic Case Of Idiopathic Intracranial Hypertension

Idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure (ICP) in the absence of any known causative factor. Severe headache and visual field disturbance are usually the primary symptoms. If high ICP is left untreated, there is a high risk of continued visual deterioration with risk of blindness. IIH is primarily managed medically. Surgery (CSF diversion procedures with lumboperitoneal shunting or ventriculoperitoneal shunting and optic nerve fenestration) is reserved for patients who have failed medical therapy (20%). Endovascular stenting of the dural venous sinus stenosis in cases of documented venous pressure gradient has shown significant promise in a select subgroup of patients, both in terms of visual and headache outcomes.
