Intraosseous dural arteriovenous fistulas (DAVFs) are distinct in that the fistula is located within the bone rather than the dura through which the dural vessels pass. It has been stated that only fistulas within marrow should be considered as intraosseous DAVFs rather than DAVFs with traditional angioarchitecture that erode into bone or are located within a bony foramen. The ambiguity in the definition may have contributed to the oversight and scarcity of relevant cases reported in the literature. Three- or four-dimensional digital subtraction angiography is useful for determining the location of the fistula and developing treatment plans. We present an intraosseous DAVF around the pterygopalatine fossa using a transvenous approach.
骨内硬脑膜动静脉瘘 (DAVF) 的特点是瘘口位于骨内，而不是硬脑膜内，硬脑膜内是硬脑膜血管通过的地方。有人指出，只有位于骨髓内的瘘口才应被视为骨内 DAVF，而不是具有传统血管结构侵蚀入骨或位于骨孔内的 DAVF。定义上的模糊性可能导致文献中报道的相关病例被忽视和稀少。三维或四维数字减影血管造影术有助于确定瘘口的位置并制定治疗计划。我们采用经静脉入路报道了一例翼腭窝周围的骨内 DAVF。
