Two cases of hypoglossal canal dural arteriovenous fistulas (HCDAVF) were reported. The clinical manifestation, radiological features, treatment and prognosis were reviewed. Both cases presented chemosis and pulsatile tinnitus. 3D-time-of-flight (TOF) magnetic resonance angiography (MRA) demonstrated abnormal high signal in hypoglossal canal. Cerebral digital subtraction angiography (DSA) showed that these HCDAVFs were supplied by multiple intracranial and extracranial arteries, and fistulas were located in hypoglossal canal. Fistulas were blocked by coils and Onyx-18 through transvenous approach, and the angiography after the embolism showed complete occlusion of fistula. No adverse events after treatment and no recurrence during the follow up were observed.
报告了2例舌下神经管硬脑膜动静脉瘘（HCDAVF）。回顾了其临床表现、影像学特征、治疗及预后。2例均表现为结膜水肿和搏动性耳鸣。三维时间飞跃（TOF）磁共振血管造影（MRA）显示舌下神经管内异常高信号。全脑数字减影血管造影（DSA）显示这些HCDAVF由多条颅内和颅外动脉供血，瘘位于舌下神经管。通过静脉途径用弹簧圈和Onyx-18封堵瘘口，栓塞术后血管造影显示瘘口完全闭塞。治疗后未观察到不良事件，随访期间无复发。
