BACKGROUND Idiopathic intracranial hypertension (IIH) is characterized by an elevated intracranial pressure without any identifiable causative factor such as an intracranial mass. Dural venous sinus stenosis (DVSS) has been suggested to be associated with IIH. OBJECTIVE We performed an updated systematic review and meta-analysis to determine clinical outcomes as well as stent survival and stent-adjacent stenosis rates in patients undergoing DVSS for the management of medically refractory IIH. METHODS We searched PubMed, Embase, and Cochrane databases to identify prospective or retrospective cohorts or case series of patients with IIH treated with DVSS between 2000 and 2017. RESULTS A total of 473 patients were included from 24 studies. Headache was present in 429 (91.8%) patients and resolved or improved in 319/413 (77.2%) after the procedure. Headache, papilledema, visual acuity, and tinnitus improved in 256/330 (77.6%), 247/288 (85.8%), 121/172 (70.3%), and 93/110 (84.5%) patients following DVSS at the final follow-up (mean of 18.3 months). In a meta-analysis of 395 patients with available follow-up data on stenting outcome (mean of 18.9 months), the stent survival and stent-adjacent stenosis rates were 84% (95% confidence interval [CI] 79-87%) and 14% (95% CI 11-18%), respectively. The rate of major neurological complications was less than 2%. CONCLUSION Stent-adjacent stenosis is an important complication following venous stenting in patients with DVSS and IIH. Further studies are needed to identify determinants of stent-adjacent stenosis and stent nonsurvival.

静脉窦支架置入治疗特发性颅内高压后的支架存活率和支架邻近狭窄率:系统评价和荟萃分析。

背景技术特发性颅内高压(IIH)的特征在于颅内压升高而没有任何可识别的致病因素,例如颅内肿块。硬脑膜静脉窦狭窄(DVSS)被认为与 IIH 相关。目的:我们进行了更新的系统评价和荟萃分析,以确定接受 DVSS 治疗药物难治性 IIH 的患者的临床结果以及支架存活率和支架邻近狭窄率。方法 我们搜索了 PubMed、Embase 和 Cochrane 数据库,以确定 2000 年至 2017 年期间接受 DVSS 治疗的 IIH 患者的前瞻性或回顾性队列或病例系列。结果 24 项研究共纳入 473 名患者。429 名 (91.8%) 患者出现头痛,319/413 (77.2%) 名患者在手术后缓解或改善。DVSS 后 256/330 (77.6%)、247/288 (85.8%)、121/172 (70.3%) 和 93/110 (84.5%) 的患者在最终随访时头痛、视乳头水肿、视力和耳鸣得到改善-up(平均 18.3 个月)。在一项对 395 名患者进行的荟萃分析中,有关于支架植入结果的可用随访数据(平均 18.9 个月),支架存活率和支架邻近狭窄率为 84%(95% 置信区间 [CI] 79-87%)和分别为 14% (95% CI 11-18%)。主要神经系统并发症的发生率低于 2%。结论支架邻近狭窄是DVSS和IIH患者静脉支架置入术后的重要并发症。需要进一步的研究来确定支架相邻狭窄和支架无法存活的决定因素。93/110 (84.5%) 名患者在最终随访时接受 DVSS(平均 18.3 个月)。在一项对 395 名患者进行的荟萃分析中,有关于支架植入结果的可用随访数据(平均 18.9 个月),支架存活率和支架邻近狭窄率为 84%(95% 置信区间 [CI] 79-87%)和分别为 14% (95% CI 11-18%)。主要神经系统并发症的发生率低于 2%。结论支架邻近狭窄是DVSS和IIH患者静脉支架置入术后的重要并发症。需要进一步的研究来确定支架相邻狭窄和支架无法存活的决定因素。93/110 (84.5%) 名患者在最终随访时接受 DVSS(平均 18.3 个月)。在一项对 395 名患者进行的荟萃分析中,有关于支架植入结果的可用随访数据(平均 18.9 个月),支架存活率和支架邻近狭窄率为 84%(95% 置信区间 [CI] 79-87%)和分别为 14% (95% CI 11-18%)。主要神经系统并发症的发生率低于 2%。结论支架邻近狭窄是DVSS和IIH患者静脉支架置入术后的重要并发症。需要进一步的研究来确定支架相邻狭窄和支架无法存活的决定因素。支架存活率和支架邻近狭窄率分别为 84%(95% 置信区间 [CI] 79-87%)和 14%(95% CI 11-18%)。主要神经系统并发症的发生率低于 2%。结论支架邻近狭窄是DVSS和IIH患者静脉支架置入术后的重要并发症。需要进一步的研究来确定支架相邻狭窄和支架无法存活的决定因素。支架存活率和支架邻近狭窄率分别为 84%(95% 置信区间 [CI] 79-87%)和 14%(95% CI 11-18%)。主要神经系统并发症的发生率低于 2%。结论支架邻近狭窄是DVSS和IIH患者静脉支架置入术后的重要并发症。需要进一步的研究来确定支架相邻狭窄和支架无法存活的决定因素。
