一种分类提出，统一和组织脊柱和颅硬脑膜动静脉瘘畸形（AVFMs）为三种类型的基础上，他们的解剖相似性。I型硬脑膜AVFMs直接流入硬脑膜静脉窦或脑膜静脉。II型畸形引流至硬脑膜窦或脑膜静脉，但也有逆行引流至蛛网膜下腔静脉。III型畸形流入蛛网膜下腔静脉，没有硬脑膜窦或脑膜静脉引流。这三种类型的动脉供应都来自脑膜动脉。提出了解剖基础的分类，并提出了几个案例，说明三种类型的硬脑膜AVFMs。根据脊髓和颅硬脑膜AVFMs的解剖特点，讨论了治疗的基本原理。
A classification is proposed that unifies and organizes spinal and cranial dural arteriovenous fistulous malformations (AVFMs) into three types based upon their anatomical similarities. Type I dural AVFMs drain directly into dural venous sinuses or meningeal veins. Type II malformations drain into dural sinuses or meningeal veins but also have retrograde drainage into subarachnoid veins. Type III malformations drain into subarachnoid veins and do not have dural sinus or meningeal venous drainage. The arterial supply in each of these three types is derived from meningeal arteries.The anatomical basis of the proposed classification is presented with several cases that illustrate the three types of dural AVFMs. A rationale for the treatment of spinal and cranial dural AVFMs according to their anatomical characteristics is discussed.
