Abstract
Objective: Venous structures of the transverse-sigmoid sinus region have been insufficiently studied by magnetic resonance venography, especially in the healthy Han Chinese population.
Methods: Magnetic resonance venography data were reconstructed. The relevant parameters were recorded. A paired t-test was used to compare the diameters of the inferior petrous sinus at the origin and termination. An unpaired t-test, a chi-squared test or Fisher's exact test was used to compare other data.
Results: One hundred healthy participants were included. The average age was 36.6 ± 17.1 years, and the ratio of males to females was 1:1. The development of the transverse-sigmoid sinus had a right-sided predominance in 51% of patients. Statistical analysis revealed significant differences (p < 0.05) in the lengths of bilateral TSs, the lengths of bilateral partial TSs from the torcular to lateral tentorial sinus, the diameters between bilateral TSs at the origin and the lateral tentorial sinus, the diameters between bilateral TS-sigmoid sinus junctions and sigmoid sinus terminations, and the inferior petrous sinus diameters at the origin and termination. Statistical analysis revealed that the right lateral tentorial sinus was more likely to originate from the TS (p < 0.05). Statistical analysis revealed no significant differences (p < 0.05) between transverse-sigmoid sinus development and inferior petrous sinus continuity or between transverse-sigmoid sinus development and inferior petrous sinus continuity and bilateral inferior petrous sinus continuity.
Conclusions: This study revealed that the right transverse-sigmoid sinus was predominantly larger in diameter, the torcular Herophili tended to deviate to the right, and the right lateral tentorial sinus tended to drain into the TS. The inferior petrous sinus at the origin was thicker than that at the termination, and the right inferior petrous sinus was thicker than the left inferior petrous sinus. transverse-sigmoid sinus development had no effect on inferior petrous sinus continuity, and there was no difference in inferior petrous sinus continuity between the left and right sides.
摘要磁共振静脉成像对横筛窦区域的静脉结构研究不足,尤其是在健康的中国汉族人群中:方法:重建磁共振静脉成像数据。方法:重建磁共振静脉成像数据,记录相关参数。采用配对 t 检验比较下隐静脉窦起点和终点的直径。其他数据的比较采用非配对 t 检验、卡方检验或费雪精确检验:结果:共纳入 100 名健康参与者。平均年龄为 36.6 ± 17.1 岁,男女比例为 1:1。51%的患者以右侧横筛窦发育为主。统计分析显示差异显著(P P P P 结论:这项研究显示,右侧横筛-乙状窦的直径主要较大,环状蝶窦倾向于向右侧偏斜,右侧触角窦倾向于向 TS 引流。下隐窦起始处比终止处厚,右侧下隐窦比左侧下隐窦厚。横乙状窦的发育对下隐窦的连续性没有影响,左右两侧下隐窦的连续性没有差异。
