Increased Intracranial Hypertension (IIH), also known as Pseudotumor Cerebri, is defined by increased cerebral spinal fluid (CSF) pressure in the absence of intracranial, metabolic, toxic or hormonal causes of intracranial hypertension. It is characterized by headaches, tinnitus and visual loss, due to optic atrophy, in 50% of cases. Surgical treatments, such as CSF shunt placement and optic nerve sheath fenestration (ONSF), are indicated in case of failure or non-compliance (owing to side effects) of medical treatments (that mainly includes weight loss and drugs, such as Carbonic Anhydrase Inhibitors). However, these surgical treatments are limited by relative high complications and recurrence rate. Indeed, improvement in visual function after ONSF is often transient and the risk of complications, including visual loss, pupillary dysfunction, and vascular complications is up to 40%. With no better treatment option, intraventricular or lumbar shunt placement has become the traditional treatment for medically refractory IIH, despite poor results. Indeed, series of patients with IIH treated with shunt replacement report a complications rate (shunt occlusion, disconnection, infection or intracranial hematoma formation) around 50% and a failure rate up to 64% within 6 months. As a consequence, shunt revision is often required and efficacy of the technique to control the disease is questionable.
