Abstract:
Objective To evaluate the efficacy of cerebral venous sinus pressure measurement with a microcatheter in guiding stent angioplasty for the treatment of venous sinus stenosis.Methods A total of 42 patients with idiopathic intracranial hypertension (IIH) complicated by localized venous sinus stenosis were enrolled in this study.Microcatheter venous sinus venography with DSA and venous sinus pressure measurement were performed in all patients.Of the 42 patients,the pressure difference between the distal end and the proximal end of venous sinus ＞12 mmHg was found in 32,for whom balloon dilatation together with stent angioplasty was carried out.The venous sinus pressure was measured again after the treatment.The improvement of postoperative clinical symptoms was evaluated.The occurrence of complications,the symptom relapse and the patency of venous sinus were checked up.Results Successful venous sinus stent angioplasty was achieved in all 32 patients.The symptoms of intracranial hypertension were remarkably relieved,and no procedure-related complications occurred.The postoperative pressure difference between the distal end and the proximal end of venous sinus was significantly different from the preoperative one (P＜0.05),and the pressure showed a parallel correlation with the pressure of lumbar puncture.One week after the treatment,the headache was strikingly rclieved although visual acuity showed no obvious improvement.The patients were followed up for 12 months,no recurrence of clinical symptoms was seen,and magnetic resonance venography (MRV) or DSA examination showed that venous sinus blood flow was unobstructed and no restenosis was detected.Conclusion For the treatment of IIH stenosis complicated by localized venous sinus stenosis,endovascular stent angioplasty is relatively safe and effective,and the cerebral venous sinus pressure measurement with a microcatheter is of clinical significance for the selection of suitable patients as well as for the evaluation of curative effect.
