Three cases of spontaneously closing dural arteriovenous fistulas (AVFs) are presented, and 11 previously published cases are reviewed. On the basis of clinical and angiographic data, two types of spontaneously regressing dural AVFs are distinguished: posttraumatic and spontaneous. In all cases, the explanation for spontaneous closure is unknown. Some authors have hypothesized that the thrombosis of the draining sinus could be involved. We report three cases of spontaneous dural AVF closure with conservation of sinus patency.
本文报告了3例硬脑膜动静脉瘘(AVF)自发闭合的病例,并回顾了之前发表的11例病例。根据临床和血管造影数据,区分出两种类型的硬脑膜AVF自发消退:创伤后型和自发型。在所有病例中,自发闭合的原因尚不清楚。一些作者推测可能与引流静脉窦的血栓形成有关。我们报告了3例硬脑膜AVF自发闭合且静脉窦通畅得以保留的病例。
