Two cases of a second dural arteriovenous fistula (DAVF), both developing in different locations after selective transvenous embolization of the first DAVF, are presented. One recurrent DAVF developed on the sigmoid sinus 5 months after transvenous embolization of a DAVF in the paratransverse sinus channel, and the other recurrence developed around the jugular bulb 5 months after transvenous embolization of a cavernous DAVF. The former was obliterated by a second embolization, and the latter disappeared spontaneously at 20 months.
本文报告两例硬脑膜动静脉瘘（DAVF），均在首次DAVF经静脉选择性栓塞后于不同部位复发。一例复发性DAVF发生于横窦旁通道DAVF经静脉栓塞5个月后，位于乙状窦；另一例复发发生于海绵窦DAVF经静脉栓塞5个月后，位于颈静脉球周围。前者经再次栓塞治愈，后者在20个月时自行消失。
