Vertebro-vertebral arteriovenous fistula (VV-AVF) is an uncommon vascular disorder characterized by an abnormal direct connection between the extracranial vertebral artery (VA), as well as the first and second branches of subclavian arteries, and the draining veins of the paravertebral venous plexus. Endovascular occlusion or surgical ligation of the high-flow arteriovenous fistula is the main goal of treatment for VV-AVF, but there are no guidelines for the best treatment to date. Endovascular treatment is the primary treatment procedure due to its safety, effectiveness, and simplicity. We reported a rare clinical case of the endovascular approach used for occlusion of VV-AVF. A 52-year-old female patient with no history of trauma was presented with right neck pain for a month. Diagnostic angiography demonstrated a high-flow VV-AVF at C3-C4 level. After endovascular occlusion with detachable-balloon embolization, the fistula was completely obliterated. To our knowledge, endovascular occlusion for VV-AVF patients is safe and effective. Detachable balloon embolization can be considered a well-tolerated treatment.
椎-椎动脉动静脉瘘（VV-AVF）是一种罕见的血管疾病，其特征是颅外椎动脉（VA）以及锁骨下动脉的第一和第二分支与椎旁静脉丛的引流静脉之间存在异常的直接连接。高流量动静脉瘘的血管内闭塞或手术结扎是VV-AVF治疗的主要目标，但迄今为止尚无最佳治疗指南。由于血管内治疗的安全性、有效性和简便性，它是主要的治疗方法。我们报告了一例罕见的采用血管内方法闭塞VV-AVF的临床病例。一名52岁无外伤史的女性患者出现右颈部疼痛1个月。诊断性血管造影显示C3-C4水平存在高流量VV-AVF。采用可脱性球囊栓塞进行血管内闭塞后，瘘完全闭塞。据我们所知，血管内闭塞对VV-AVF患者是安全有效的。可脱性球囊栓塞可被视为一种耐受性良好的治疗方法。
