A 72-year-old man presented with sudden right homonymous hemianopsia. Work-up imaging revealed a left occipital haematoma and an arteriovenous fistula supplied by the meningeal branches to the clivus from the left vertebral artery (VA) with a rostral venous reflux into cortical veins. A microcatheter was advanced through brainstem veins into the venous collector. A compliant balloon was placed in the left VA facing the origin of feeders. The balloon was inflated to protect the vertebrobasilar circulation from embolic migration. Onyx was injected by the transvenous catheter. Control angiogram revealed exclusion of the lesion. Informed consent was obtained from the patient.
一名72岁男性因突发右侧同向性偏盲就诊。检查性影像学显示左侧枕叶血肿以及由左侧椎动脉(VA)脑膜支供应至斜坡的动静脉瘘,并有头端静脉逆流至皮质静脉。一根微导管经脑干静脉推进至静脉收集器。在左侧椎动脉中朝向供血支起源处放置一个顺应性球囊。球囊充气以保护椎基底循环免受栓子迁移影响。通过经静脉导管注入Onyx。血管造影复查显示病变被封堵。已获得患者的知情同意。
