Regardless of the underlying pathology, elevated intracranial pressure is the endpoint of any impairment in either cerebrospinal fluid (CSF) absorption (including arachnoid villi) or intracranial venous drainage. In all age groups, the predominant final common pathway for CSF drainage is the dural venous sinus system. Intracranial venous hypertension (ICVH) is an important vascular cause of intracranial hypertension (and its subsequent sequelae), which has often been ignored due to excessive attention to the arterial system and, specifically, arteriovenous shunts. Various anatomical and pathological entities have been described to cause ICVH. For the second time, we present a unique case of severe focal stenosis in the distal sigmoid sinus associated with concurrent hypoplasia of the contralateral transverse sinus causing a significant pressure gradient and intracranial hypertension, which was treated with endovascular stent placement and angioplasty.
无论潜在的病理情况如何，颅内压升高都是脑脊液（CSF）吸收（包括蛛网膜绒毛）或颅内静脉引流出现任何损害的最终结果。在所有年龄组中，CSF引流的主要最终共同途径是硬脑膜静脉窦系统。颅内静脉高压（ICVH）是颅内高压（及其后续后遗症）的一个重要血管性病因，由于过度关注动脉系统，特别是动静脉分流，它常常被忽视。已描述了多种解剖学和病理学实体可导致ICVH。我们再次报告了一例独特的病例，即乙状窦远端严重局灶性狭窄，同时对侧横窦发育不全，导致显著的压力梯度和颅内高压，该病例通过血管内支架置入和血管成形术进行了治疗。
