Dural arteriovenous fistulae (DAVF) of the hypoglossal canal region are rare lesions. We describe three cases of DAVF of the hypoglossal canal presenting with ocular symptoms and discuss the endovascular management options.
Three consecutive patients with DAVF of the hypoglossal canal region presented with proptosis, chemosis and disturbances of extra-ocular mobility. Each patient was treated using a different endovascular approach, based on variations of the vascular access.
The cases and treatments are reviewed, with a literature review on the subject. Endovascular treatment, transvenous or trans-arterial was curative in all cases.
DAVF of the hypoglossal canal region can present with ocular manifestations very similar to DAVF of the cavernous sinus or carotid-cavernous fistulas. Endovascular treatment is usually feasible and effective, but an understanding of the vascular anatomy and pathophysiology of the disease are of utmost importance when planning the approach.
舌下神经管区域的硬脑膜动静脉瘘（DAVF）是罕见的病变。我们描述三例表现为眼部症状的舌下神经管DAVF病例，并讨论血管内治疗方案。
连续三例舌下神经管区域DAVF患者表现为眼球突出、结膜水肿和眼球运动障碍。根据血管入路的不同，每位患者采用不同的血管内治疗方法。
回顾了病例及治疗情况，并对该主题进行了文献综述。经静脉或经动脉的血管内治疗在所有病例中均治愈。
舌下神经管区域的DAVF可表现出与海绵窦DAVF或颈动脉海绵窦瘘非常相似的眼部表现。血管内治疗通常可行且有效，但在规划治疗方案时，了解该疾病的血管解剖和病理生理学至关重要。
