The dural venous sinuses (DVS), in general, are frequently asymmetrical and display far more anatomical variations than arterial systems. A comprehensive study of the anatomy and variants of the DVS can help surgeons in the preoperative evaluation and management as well as minimizing possible complications in the following treatment.
The current review was designed to provide a general overview of the normal anatomy and notable variants of the cerebral venous system as surveyed from the available literature. The pros and cons of different multimodal imaging methods for investigating DVS are also outlined. Finally, cases of various pathological entities are illustrated from our clinical practice.
There are many anatomical variations and lesions involving the DVS. MRI examination can provide essential information both on anatomical variation and morphological or functional change of the offending DVS in most circumstances. Multimodal non-invasive venography protocols may become a feasible alternative to the classical digital subtraction angiography and would improve the diagnostic accuracy in future studies.
硬脑膜静脉窦（DVS）通常不对称，其解剖变异比动脉系统多得多。全面研究 DVS 的解剖结构和变异有助于外科医生在术前评估和管理，以及在后续治疗中尽量减少可能出现的并发症。
本综述旨在提供硬脑膜静脉系统的正常解剖结构和显著变异的概述，这是从现有文献中调查得出的。还概述了不同多模态成像方法在研究 DVS 中的优缺点。最后，从我们的临床实践中展示了各种病理实体的病例。
DVS 存在许多解剖变异和病变。在大多数情况下，MRI 检查可以提供关于解剖变异和受累 DVS 的形态或功能变化的重要信息。多模态非侵入性静脉造影方案可能成为经典数字减影血管造影的可行替代方案，并将提高未来研究的诊断准确性。
