Carotid-cavernous fistulas (CCFs) are an abnormal vascular shunt between the carotid artery and the cavernous sinus, and were traditionally classified into four subtypes based on the detailed fistulas anatomy and arterial supply. CCFs are frequently encountered in patients with traumatic skull base fractures. In this report, we present one such case caused by two head traumas. Computed tomography and digital subtraction angiography confirmed that this CCF arose from posterior communicating artery of the internal carotid artery, which is not included in the traditional Barrow et al's categorization. The possible mechanisms include laceration of dural mater of posterior clinoid process and laceration or pseudoaneurysm formation of posterior communicating artery. This case was successfully treated with endovascular coil embolization.
颈动脉海绵窦瘘（CCFs）是颈动脉与海绵窦之间的一种异常血管分流，传统上根据瘘管的详细解剖结构和动脉供应分为四种亚型。CCFs在创伤性颅底骨折患者中很常见。在本报告中，我们介绍了一例由两次头部外伤引起的此类病例。计算机断层扫描和数字减影血管造影证实，该CCF起源于颈内动脉后交通动脉，这并不包括在传统的巴罗等人的分类中。可能的机制包括后床突硬脑膜撕裂以及后交通动脉撕裂或假性动脉瘤形成。该病例通过血管内弹簧圈栓塞术成功治疗。
