Idiopathic Intracranial Hypertension

Area of Science:

• Neurology
• Ophthalmology
• Vascular Surgery

Background:

• Idiopathic intracranial hypertension (IIH) is a poorly understood neurological disorder characterized by elevated intracranial pressure.
• IIH disproportionately affects obese women, with incidence rising globally alongside obesity rates.
• Limited understanding of IIH pathophysiology necessitates improved diagnostic and management strategies.

Purpose of the Study:

• To summarize the epidemiology, clinical features, diagnostic evaluation, and management of IIH.
• To highlight venous sinus stenting as a promising therapeutic option for IIH.

Main Methods:

• Review of current literature on IIH epidemiology, clinical presentation, and diagnostic criteria.
• Analysis of medical and surgical management options, including pharmacological treatments and interventional procedures.
• Focus on the safety and efficacy of venous sinus stenting in IIH management.

Main Results:

• IIH incidence correlates with increasing global obesity levels.
• Acetazolamide and topiramate are primary medical treatments; surgery is reserved for refractory or severe cases.
• Venous sinus stenting is increasingly utilized as a safe and effective surgical alternative for IIH.

Conclusions:

• A lack of randomized controlled trials hinders definitive treatment guidelines for IIH.
• While venous sinus stenting shows promise for refractory IIH, procedural variability exists.
• Further research is needed to standardize venous sinus stenting techniques and outcomes in IIH.
