Abstract

Background: Raised intracranial pressure [ICP] without any defined clinical or radiological signs of space-occupying intracranial lesions and with normal cerebrospinal fluid [CSF] examination is characterized as idiopathic intracranial hypertension [IIH]. We aimed to assess the venous sinus stenting effectiveness in the IIH treatment.
Patients and Methods: This case control study was conducted on 10 patients with IIH. The subjects were categorized into two groups [one control group and one study group] both matched in in demographics. The control group: received traditional IIH treatment for three months, while the study group received traditional IIH treatment, as well as undergoing venous sinus stent for three months. All patients were subjected to full neurological and general examination, detailed neurological and medical history, and headache disability assessment and Headache Impact Test [HIT-6] questionnaire.
Results: In the stent group, there was an improvement in the papilledema level as follows; two [20%] patients reach normal fundus examination, 2 [40%] patients with papilledema grade I, 1 [20%] with grade II and. The headache [HIT] score also improved to 59.3 without any reported other type of headache. We found a right transverse sinus [TS] attenuation in three patients and left TS attenuation in two patients. There was an improvement in the CSF pressure by 9.8±1.3 mmH2O. Also, there was improvement in the radiological findings in the form of absence of that Empty Sella, tortuous veins, and flatting of the globe.
Conclusion: All of our patients have benefited from and responded to stenting quite well, with positive outcomes. Numerous investigations have shown that there are no intraoperative problems after venous stenting for IIH.
