Some have suggested that trabeculae within the transverse sinuses (chordae Willisii) might restrict flow and potentially contribute to thrombus organization. In addition, these structures might be encountered with endovascular procedures within the transverse sinus and are now readily seen on imaging. Therefore as anatomic studies of these structures are scant, the current study aimed to better elucidate these structures within the transverse sinus via a morphologic study in cadavers.
Thirty fresh-frozen, cadaveric transverse sinuses were dissected, and their detailed morphology was recorded. Classification schemes were applied based on the anatomy and orientation of each chordae.
Chordae were found on 70% of sides and were statistically more likely to be found on right sides (86.6%) (P < 0.01). Three types and 3 classes of chordae were identified. There was a statistically significant difference between sides regarding type of chordae (P = 0.02).
To date, a comprehensive anatomic evaluation of the intraluminal chordae of the transverse sinuses has been lacking. Knowledge of these bands is also essential to those performing endovascular procedures of the dural venous sinuses and for those interpreting imaging of these structures.
一些人认为横窦内的小梁（威利斯氏索）可能会限制血流，并可能促进血栓机化。此外，在横窦内进行血管内手术时可能会遇到这些结构，并且现在在影像学上很容易看到。因此，由于对这些结构的解剖学研究较少，本研究旨在通过对尸体的形态学研究更好地阐明横窦内的这些结构。
解剖30个新鲜冷冻的尸体横窦，并记录其详细形态。根据每条索的解剖结构和方向应用分类方案。
在70%的侧别中发现了索，并且在统计学上右侧更有可能发现索（86.6%）（P < 0.01）。确定了三种类型和三级索。两侧索的类型在统计学上有显著差异（P = 0.02）。
迄今为止，缺乏对横窦腔内索的全面解剖学评估。对于进行硬脑膜静脉窦血管内手术的人员以及解读这些结构影像学的人员来说，了解这些条索也至关重要。
