OBJECTIVES
The aim of the present study was to examine the superior sagittal sinus (SSS) and bridging veins (BVs) from an anatomical, neurosurgical and radiological perspective.
METHODS
Computed tomography venographies (CTVs) of 30 patients and 9 cadaveric dissections of human SSS were analyzed.
RESULTS
CTV and cadavers showed most BVs emptying into the SSS close by (±3 cm) and distal to the coronary suture (74% in CTV, 62% in cadavers).
CONCLUSIONS
Important anatomical information can be drawn from cerebral CTV for neurosurgical preoperative planning.
目的
本研究旨在从解剖学、神经外科学和放射学角度研究上矢状窦（SSS）和桥静脉（BVs）。
方法
对 30 名患者的计算机断层静脉造影（CTV）和 9 例人体 SSS 尸体解剖进行分析。
结果
CTV 和尸体显示，大多数 BV 靠近（±3cm）且远于冠状缝（74%在 CTV 中，62%在尸体中）处排入 SSS。
结论
脑 CTV 可提供重要的神经外科术前计划解剖学信息。
