Cerebral dural arteriovenous fistulas (DAVFs) are vascular lesions consisting of a pathologic high-flow connection between dural arteries and veins or dural sinuses. Small DAVFs shunts have been demonstrated to exist physiologically, but as their estimated diameter is around 8-12 μm, they are not visible even on high-quality angiography studies.
We report 2 cases of immediate development of a DAVF after embolization with microparticles of the middle meningeal artery for treatment of chronic subdural hematoma.
This report represents the first description of sudden development of a DAVF after endovascular embolization of an intracranial artery and may shed light on the pathophysiology and development of DAVFs.
硬脑膜动静脉瘘（DAVFs）是一种由硬脑膜动脉和静脉或硬脑膜窦之间病理性高流量连接组成的血管病变。已经证明小的 DAVFs 分流在生理上存在，但由于其估计直径约为 8-12μm，即使在高质量的血管造影研究中也无法看到。
我们报告了 2 例因慢性硬脑膜下血肿而用中脑膜动脉微球栓塞后立即发生 DAVF 的病例。
本报告首次描述了颅内动脉血管内栓塞后 DAVF 的突然发展，可能有助于阐明 DAVF 的病理生理学和发展。
