OBJECTIVE
This study was performed to investigate the dynamics of intracranial pressure (ICP) alterations and bilateral transverse-sigmoid sinus morphologies in patients with venous pulsatile tinnitus (PT).
METHODS
This retrospective study involved 27 patients with venous PT associated with sigmoid sinus wall anomalies. ICP and ICP metrics were measured by cerebrospinal fluid manometry and internal jugular vein compression tests. Correlation analysis was performed to determine the statistical correlation between ICP and the morphological metrics.
RESULTS
The mean ICP was 212.5 ± 47.3 mmHO. The median was 130 (range, 55-150) mmHO. The was linearly correlated with the open lumbar pressure, and a significant difference was found between patients with normal and elevated cerebrospinal fluid pressure. The was linearly correlated with the and . was linearly correlated with
CONCLUSIONS
Complete obstruction of flow patency should be avoided in patients with low ICP and large volumetric/patency differences in the bilateral transverse-sigmoid sinus systems.
目的
本研究旨在探讨伴有乙状窦壁异常的静脉性搏动性耳鸣（PT）患者颅内压（ICP）变化和双侧横窦形态的动力学变化。
方法
本回顾性研究纳入了 27 例伴有乙状窦壁异常的静脉性 PT 患者。通过脑脊髓液测压和颈内静脉压迫试验测量 ICP 和 ICP 指标。进行相关性分析，以确定 ICP 与形态学指标之间的统计学相关性。
结果
平均 ICP 为 212.5 ± 47.3 mmHO。中位数为 130（范围，55-150）mmHO。与开放腰椎压力呈线性相关，且在脑脊液压力正常和升高的患者之间存在显著差异。与 和 呈线性相关。与 呈线性相关。
结论
在 ICP 较低且双侧横窦系统容积/通畅性差异较大的患者中，应避免完全阻塞血流通畅性。
