A Case of Stent Placement for Intracranial Hypertension Associated with Venous Sinus Stenosis

抄録

Objective: We encountered a patient with chronic headache due to intracranial hypertension associated with venous sinus stenosis. The symptom was alleviated after stent placement at the site of stenosis.

Case Presentation: The patient was a 33-year-old man with chronic headache as a chief complaint. MRI revealed stenosis of the right transverse and occipital sinuses. Intracranial hypertension was diagnosed by a lumbar puncture. Although lumboperitoneal shunting was performed after conservative treatment, no symptomatic improvement was observed. The venous pressure was measured at the time of cerebral angiography. Since intracranial hypertension and a transstenotic venous pressure gradient were observed, stent placement was performed, resulting in alleviation of headache.

Discussion: Transverse sinus stenosis can be a cause of intracranial hypertension although rarely. Stent placement is considered to be a treatment worth attempting in patients who resist medical treatments or cerebrospinal fluid shunting.
