Spontaneous or traumatic arteriovenous fistulae between vertebral artery and the surrounding venous plexus may cause vertebrobasilar hypoperfusion by steal effects. We report on a 71-year-old man presenting with vertigo. Duplex sonography revealed a vertebral arteriovenous fistula at the C4/5 level with the typical perivascular color Doppler artifact and hyperperfusion in the supplying arteries and draining veins. Angiography confirmed the findings; the consequently performed endovascular embolization using platin coils and silicon balloon removed the symptoms immediately. Ultrasonographic follow-up examinations within 5 months demonstrated the success of therapy showing only low-flow fistula yet. This case demonstrates that early detection of a vertebral arteriovenous fistula by duplex sonography is highly beneficial because efficient treatment modalities are available.
椎动脉与周围静脉丛之间的自发性或创伤性动静脉瘘可通过盗血效应导致椎基底动脉灌注不足。我们报告一例71岁男性，以眩晕为主要表现。双功超声检查显示在C4/5水平存在椎动脉动静脉瘘，伴有典型的血管周围彩色多普勒伪像，供血动脉和引流静脉内血流灌注增加。血管造影证实了上述发现；随后使用铂圈和硅胶球囊进行血管内栓塞治疗，症状立即消失。5个月内的超声随访检查显示治疗成功，此时仅存在低流量瘘。该病例表明，双功超声早期发现椎动脉动静脉瘘非常有益，因为已有有效的治疗方法。
