The filum terminale is an anatomic structure at the end of the spinal cord. Only a few cases of AVFs of the filum terminale have been reported. These AVFs usually consist of a single communication between the anterior spinal artery and a single draining vein. We retrospectively analyzed the clinical and radiologic features and treatment of 4 patients with spinal AVFs of the filum terminale. Clinical manifestations and MR images are similar to those of spinal dural AVFs. All patients underwent surgical or endovascular treatment, resulting in complete occlusion. Clinical outcomes were good to excellent in all patients.
终丝是脊髓末端的解剖结构。仅有少数终丝动静脉瘘（AVF）的病例报告。这些动静脉瘘通常由单一的脊髓前动脉和单一的引流静脉之间的沟通组成。我们回顾性分析了 4 例终丝脊髓动静脉瘘患者的临床和影像学特征及治疗方法。临床表现和磁共振成像与脊髓硬脊膜动静脉瘘相似。所有患者均接受手术或血管内治疗，结果完全闭塞。所有患者的临床结果均良好至优。
