Treatment of refractory idiopathic intracranial hypertension (ⅡH) is a challenging problem.We reported a refractory ⅡH patient who manifested with typical intracranial hypertensive symptoms successfully treated with endovascular stent implantation.Pre-operative cerebrospinal fluid (CSF) opening pressure is 36 cmH2O.Cerebral angiography demonstrated a stenotic lesion located at the right transverse sinus (TS).The stenotic TS reted to its normal caliber and the pressure gradient deceased from 36 mmHg to 4 mmHg after the stent placement.The intracranial hypertensive svmotoms resolved and one month later,the CSF opening pressure decreased to 14 cmH2O.
