Idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure without a clear cause, often linked to cerebral venous sinus constriction from embryological or acquired factors. Although less common, brain tumors like parasagittal meningiomas can compress the superior sagittal sinus, leading to IIH. Venous stenting has become a minimally invasive and effective intervention for managing IIH caused by superior sagittal sinus stenosis, particularly when residual meningiomas continue to exert pressure on the sinus.1-6 Video 1 presents a step-by-step technique for deploying dual Onyx cardiac stents to treat stenosis in the superior sagittal sinus, which is complemented by middle meningeal artery embolization. This helps to reduce the vascular supply to the remaining meningioma tissue. This combined approach not only provides immediate relief from IIH symptoms but also minimizes surgical risks, such as venous infarction and excessive blood loss. It serves as a valuable adjunct in cases where complete surgical tumor removal is challenging. neurintsurg;17/8/795/V1F1V1Video 1- Techinical video of a case of superior sagittal sinus stenosis from an invasive meningioma causing intracranial hypertension successfully treated with a coronary balloon mounted stent.
特发性颅内高压(IIH)的特征是颅内压升高但无明确病因,常与胚胎学或后天因素导致的脑静脉窦狭窄有关。虽然不太常见,但矢状窦旁脑膜瘤等脑肿瘤可压迫上矢状窦,导致IIH。静脉支架置入术已成为治疗由上矢状窦狭窄引起的IIH的一种微创且有效的干预措施,特别是当残留脑膜瘤继续对窦施加压力时。1 - 6视频1展示了部署双枚Onyx心脏支架治疗上矢状窦狭窄的分步技术,并辅以脑膜中动脉栓塞。这有助于减少对剩余脑膜瘤组织的血管供应。这种联合方法不仅能立即缓解IIH症状,还能将静脉梗死和失血过多等手术风险降至最低。在完全切除肿瘤具有挑战性的病例中,它是一种有价值的辅助手段。神经外科手术;17/8/795/V1F1V1视频1 - 一例因侵袭性脑膜瘤导致颅内高压的上矢状窦狭窄病例,成功使用冠状动脉球囊支架治疗的技术视频
