Dural arteriovenous fistulas (dAVFs) are aberrant vascular communications between meningeal arteries and venous sinuses or cortical veins. dAVF pathogenesis is incompletely understood; however, formation likely occurs as a result of angioneogensis.
A 78-year-old man presented after trauma with basal and cortical subarachnoid hemorrhage (SAH). Computed tomography revealed a parietal bone fracture overlying the superior sagittal sinus (SSS). Catheter angiography performed within 24 hours of the injury demonstrated an SSS dAVF supplied by the middle meningeal artery, adjacent to the fracture.
The authors present the case of an acute traumatic dAVF adjacent to a calvarial fracture. In this case, the authors proprose that the underlying pathogenesis is suggestive of direct vessel injury rather than the pathway commonly associated with this pathology.
硬脑膜动静脉瘘（dAVF）是脑膜动脉与静脉窦或皮质静脉之间的异常血管交通。dAVF的发病机制尚未完全明确；然而，其形成可能是血管生成的结果。
一名78岁男性在创伤后出现基底节和皮质下蛛网膜下腔出血（SAH）。计算机断层扫描显示上矢状窦（SSS）上方的顶骨骨折。受伤后24小时内进行的导管血管造影显示，与骨折相邻的SSS dAVF由脑膜中动脉供血。
作者介绍了一例与颅骨骨折相邻的急性创伤性dAVF病例。在本病例中，作者提出其潜在的发病机制提示为直接血管损伤，而非与该病理状况通常相关的途径。
