Vertebro-vertebral fistulas (VVFs) are uncommon vascular pathology. It can be either primary (spontaneous) or secondary (iatrogenic or mechanical trauma). Spontaneous vertebral arteriovenous malformation is often associated with connective tissue disorders. Cases associated with neurofibromatosis type I (NF I) are even rarer. Management of VVF with covered stent is an emerging option for construction of vertebral artery. It not only preserves the flow of the parent artery but also has immediate exclusion of the fistula from the parent artery. A 30-year-old pregnant female patient presented with cervical bruit and left upper limb radiculopathy. She was a known case of NF I. Magnetic resonance imaging cervical spine revealed multiple flow voids compressing the cervical spinal cord and nerve roots. Digital subtraction angiography revealed a vertebral artery arteriovenous fistula. She underwent endovascular treatment in the form of a covered stent. Her clinical symptoms immediately improved. She was asymptomatic at the 1-year follow-up.
椎-椎瘘（VVFs）是一种罕见的血管病变。它可以是原发性（自发性）的，也可以是继发性（医源性或机械性创伤）的。自发性椎动脉畸形常与结缔组织疾病相关。与I型神经纤维瘤病（NF I）相关的病例更为罕见。使用覆膜支架治疗VVF是一种新兴的椎动脉重建选择。它不仅能保留供血动脉的血流，还能立即将瘘管与供血动脉隔离开来。一名30岁的怀孕女性患者出现颈部杂音和左上肢神经根病。她是NF I的已知病例。颈椎磁共振成像显示多个流空影压迫颈脊髓和神经根。数字减影血管造影显示椎动脉动静脉瘘。她接受了覆膜支架形式的血管内治疗。她的临床症状立即得到改善。在1年的随访中她无症状。
