A trigeminal artery as the most common persisting embryonic carotid-basilar anastomosis is found in up to .2% of adults. In rare instances, trigeminal-cavernous fistulas develop either spontaneously or after a trauma.
We present a 16-year-old patient with a traumatic trigeminal-cavernous fistula (Saltzmann type 2), which was successfully treated by interventional occlusion of the persistent trigeminal artery. After intervention, clinical symptoms (chemosis, right-temporal bruits, and sixth nerve palsy) resolved.
In this case, fistula occlusion was achieved by coil embolization with only 4 coils placed directly at the rupture point of the trigeminal artery but not into the cavernous sinus. Thus, the cavernous sinus was preserved in function and structure. Special anatomy and interventional peculiarities of this unique case are described in detail.
作为最常见的持续胚胎颈内动脉-基底动脉吻合，三叉动脉在高达 2%的成年人中存在。在极少数情况下，三叉-海绵窦瘘会自发或外伤后形成。
我们报告了一例 16 岁患者的外伤性三叉-海绵窦瘘（Saltzmann 2 型），通过持续三叉动脉的介入闭塞治疗获得成功。介入治疗后，临床症状（球结膜水肿、右侧颞部杂音和第六脑神经麻痹）得到缓解。
在本例中，通过仅在三叉动脉破裂处直接放置 4 个线圈进行线圈栓塞来实现瘘管闭塞，而不是进入海绵窦。因此，海绵窦在功能和结构上得以保留。详细描述了这个独特病例的特殊解剖结构和介入特点。
