Endovascular treatment of idiopathic intracranial hypertension

The importance of venous sinus disease in the etiology of idiopathic intracranial hypertension is probably underestimated. Patients with idiopathic intracranial hypertension in whom a venous sinus stenosis is demonstrated by a noninvasive radiologic workup should be evaluated with direct retrograde cerebral venography and manometry. In patients with a lesion of the venous sinuses who experienced medical treatment failure, endovascular stent placement seems to be an interesting alternative to classic surgical approaches.
