This study aimed to define the patterns of basal cerebral venous drainage (BCVD) from cavernous sinus dural arteriovenous fistulas (CSDAVFs).
Forty sets of selective angiographic data from 36 patients with spontaneous CSDAVFs (age range, 53-79 years) were retrospectively analyzed for their drainage patterns. Three types of BCVD were observed, i.e., superolateral type, BCVD via the deep middle cerebral vein or uncal vein; posterolateral type, BCVD via the superior petrosal sinus and petrosal vein; and posteromedial type, BCVD via the bridging vein and the anterior pontomesencephalic vein. MR images and/or 3D-DSA images were also reviewed when available.
BCVD from CSDAVF was found in 12 patients (30%), and the other drainage routes included the superior ophthalmic vein in 25 (63%), the inferior petrosal sinus in 17 (43%), the superficial middle cerebral vein in 17 (43%), intercavernous sinus in 15 (38%), the superior petrosal sinus in seven (18%), and pterygoid plexus in two (5%), respectively. In 12 patients with BCVD, superolateral type was found in four (33%), posterolateral type in five (42%), and posteromedial type in seven (58%). Four cases of posteromedial type were associated with other types of BCVD.
CSDAVFs are often associated with BCVD via three different pathways. The posteromedial type via the bridging vein is the most frequent type of BCVD.
本研究旨在明确海绵窦硬脑膜动静脉瘘（CSDAVF）的基底脑静脉引流（BCVD）模式。
回顾性分析36例自发性CSDAVF患者（年龄范围53 - 79岁）的40组选择性血管造影数据，以观察其引流模式。观察到三种类型的BCVD，即：上外侧型，通过大脑中深静脉或钩静脉进行BCVD；后外侧型，通过岩上窦和岩静脉进行BCVD；后内侧型，通过桥静脉和脑桥前中脑静脉进行BCVD。如有可用的磁共振成像（MR）图像和/或三维数字减影血管造影（3D - DSA）图像，也进行了回顾。
12例患者（30%）发现有CSDAVF的BCVD，其他引流途径分别包括眼上静脉25例（63%）、岩下窦17例（43%）、大脑中浅静脉17例（43%）、海绵间窦15例（38%）、岩上窦7例（18%）和翼静脉丛2例（5%）。在12例有BCVD的患者中，上外侧型4例（33%），后外侧型5例（42%），后内侧型7例（58%）。4例后内侧型与其他类型的BCVD相关。
CSDAVF常通过三种不同途径与BCVD相关。通过桥静脉的后内侧型是BCVD最常见的类型。
