Intracranial Venous Stenting Evaluation in Patients With Idiopathic Intracranial Hypertension in the Early Phase

This study is testing whether placing a stent (a small tube to open a narrowed vein) in the brain can help people newly diagnosed with idiopathic intracranial hypertension (IIH) — a condition where pressure inside the skull is too high for no known reason. The stent would go in a vein called the transverse sinus to improve drainage. **You may be eligible if...** - You are 18 or older - You were diagnosed with IIH within the last 3 months - Brain imaging shows narrowing in a specific vein (transverse sinus) - You have eye-related symptoms of IIH, including swelling of the optic nerve (papilledema) - Your MRI is otherwise normal except for IIH-related findings **You may NOT be eligible if...** - Your IIH was diagnosed more than 3 months ago - You have damage to the light-sensitive cells in your eye (macular ganglion cell atrophy) - You are unable to attend all required study visits Talk to your doctor to see if this trial is right for you.
