Endovascular treatment of sigmoid sinus stenosis in benign intracranial hypertension

Abstract

Sinovenous stenosis is suggested to be related to benign intracranial hypertension. Endovascular treatment is effective in improving vision by overcoming these stenoses. We reported a case of benign intracranial hypertension with underlying right sigmoid sinus stenosis and left hypoplastic transverse sinus. Angioplasty for the right sigmoid sinus stenosis was carried out and the patient's vision improved. However, the intracranial pressure was still high approximately 1 year after angioplasty.
