The superior sagittal sinus (SSS) is an important structure, but few studies have analyzed it using computed tomography angiography (CTA).
This study was performed to examine the angiographic anatomy of the SSS and its adjacent structures using CTA in Han Chinese participants. According to age, participants were divided into elderly and nonelderly groups. The parameters of the SSS and adjacent structures were measured, recorded and analyzed statistically.
A total of 500 Han Chinese participants were enrolled in this study, including 346 in the elderly group and 154 in the nonelderly group. In the elderly group, regarding inferior sagittal sinus (ISS) development, 187 ISSs were absent, 85 were visible, and 74 were clear. In the nonelderly group, 62 ISSs were absent, 54 were visible, and 38 were clear. In the elderly group, the Rolandic bridging vein diameter was 3.6 ± 0.8 mm; in the nonelderly group, the diameter was 3.9 ± 1.1 mm. The statistical results showed a difference in ISS development between the elderly and nonelderly groups (P < 0.05). The relationship of age with ISS development was assessed using linear regression analysis, and the results indicated that ISS became gradually occluded with age (P < 0.05). The statistical results also showed a difference in the Rolandic bridging vein diameter between the elderly and nonelderly groups (P < 0.05). The relationship of age with the Rolandic bridging vein diameter was assessed using linear regression analysis, and the results indicated that the Rolandic bridging vein tended to become thinner with age (P < 0.05).
This study found that more ISSs may become occluded and that the Rolandic bridging vein may become thinner with age. Other parameters of the SSS and its adjacent structures may not be affected by aging. In addition, our study also provided normal CTA parameters of the SSS and its adjacent structures in Han Chinese people.
上矢状窦（SSS）是一个重要结构，但很少有研究使用计算机断层血管造影（CTA）对其进行分析。
本研究旨在利用CTA检查汉族参与者的上矢状窦及其相邻结构的血管造影解剖结构。根据年龄，将参与者分为老年组和非老年组。对上矢状窦及其相邻结构的参数进行测量、记录并进行统计学分析。
本研究共纳入500名汉族参与者，其中老年组346名，非老年组154名。在老年组中，关于下矢状窦（ISS）的发育情况，187个下矢状窦未显示，85个可见，74个清晰。在非老年组中，62个下矢状窦未显示，54个可见，38个清晰。在老年组中，中央沟桥静脉直径为3.6±0.8mm；在非老年组中，直径为3.9±1.1mm。统计结果显示老年组和非老年组在下矢状窦发育方面存在差异（P<0.05）。采用线性回归分析评估年龄与下矢状窦发育的关系，结果表明下矢状窦随年龄增长逐渐闭塞（P<0.05）。统计结果还显示老年组和非老年组在中央沟桥静脉直径方面存在差异（P<0.05）。采用线性回归分析评估年龄与中央沟桥静脉直径的关系，结果表明中央沟桥静脉随年龄增长有变细的趋势（P<0.05）。
本研究发现，随着年龄增长，更多的下矢状窦可能会闭塞，中央沟桥静脉可能会变细。上矢状窦及其相邻结构的其他参数可能不受衰老影响。此外，我们的研究还提供了汉族人群上矢状窦及其相邻结构的正常CTA参数。
