Spontaneous arterio-venous fistulae of the vertebral artery are rare. These lesions mainly affect the upper cervical area, and are usually asymptomatic, or may present as small, often pulsatile, cervical masses with vascular murmurs. The authors report on two cases in which the presumptive diagnosis, suggested by venous digital subtraction angiography, was then confirmed by selective angiography. In both cases an intravascular approach with detachable balloons and particulate substances was carried out, with good anatomical and functional results. Problems related to diagnosis, pathophysiology of symptoms, indications for treatment and embolization techniques are discussed.
椎动脉自发性动静脉瘘很少见。这些病变主要影响上颈部区域，通常无症状，或可能表现为小的、常呈搏动性的颈部肿块并伴有血管杂音。作者报告了两例病例，静脉数字减影血管造影提示的初步诊断随后经选择性血管造影得以证实。两例均采用可脱性球囊和颗粒物质进行血管内治疗，取得了良好的解剖和功能效果。文中讨论了与诊断、症状的病理生理学、治疗指征及栓塞技术相关的问题。
