Abstract：
Due to a unique cortical venous drainage pattern without sinus drainage, ethmoidal dural arteriovenous fistula (DAVF) are uncommon cerebral vascular lesions that carry a high risk of brain bleeding and neurologic deficit. Surgical intervention has been found to have a lower complication rate and a more satisfactory obliteration rate than endovascular treatment among the various DAVF treatment options. The supraorbital keyhole subfrontal approach is one of the least invasive and appropriate surgical techniques for addressing the anterior fossa vascular lesion in eDAVFs. We describe two men, ages 60 and 71, who underwent this surgical intervention to treat asymptomatic Cognard type IV eDAVFs. Complete obliteration with a detached fistulous point and skeletonization was accomplished with the aid of intraoperative neuronavigation. Thus, we suggest that a suitable surgical method for the treatment of eDAVFs would be to use a supraorbital keyhole subfrontal approach.
摘要：
由于独特的皮质静脉引流模式没有鼻窦引流，筛骨硬膜动静脉瘘（DAVF）是罕见的脑血管病变，具有脑出血和神经功能缺损的高风险。已发现在各种DAVF治疗方案中，与血管内治疗相比，手术干预具有较低的并发症发生率和更令人满意的闭塞率。眶上锁孔额下入路是解决eDAVFs前窝血管病变的微创和适当的手术技术之一。我们描述了两个男人，年龄分别为60岁和71岁，他们接受了这种手术干预以治疗无症状的CognardIV型eDAVF。在术中神经导航的帮助下，通过分离的瘘管点和骨骼化完成了完全的闭塞。因此，我们建议，治疗eDAVFs的合适手术方法是使用眶上锁孔额下入路。
