Brain AVMs are a rare cause of cerebral hemorrhage and SAH, and their treatment is still debated. The aim of this study was to describe a novel endovascular approach with transvenous embolization of deep hemorrhagic brain AVMs. Five patients (3 females, 2 males; mean age, 33.2 years) underwent a transvenous embolization of a deep hemorrhagic brain AVM at our institution between February and April 2012. Clinical and angiographic data at the end of the procedure and after 6 months are reported. All the AVMs were completely obliterated, and no intra- or postprocedural complications occurred. The clinical outcome was unchanged or improved in all patients. Transvenous endovascular treatment may be considered in small, hemorrhagic, and deep AVMs with single deep drainage in those cases in which neurosurgical and radiosurgical treatment might not be indicated.
脑动静脉畸形是脑出血和蛛网膜下腔出血的罕见原因，其治疗仍存在争议。本研究的目的是描述一种新的血管内治疗方法，即通过静脉途径对深部出血性脑动静脉畸形进行栓塞。2012 年 2 月至 4 月，我们机构对 5 例（3 例女性，2 例男性；平均年龄 33.2 岁）深部出血性脑动静脉畸形患者进行了静脉内栓塞治疗。报告了手术结束时和 6 个月后的临床和血管造影数据。所有动静脉畸形均完全闭塞，无术中或术后并发症发生。所有患者的临床结局均保持不变或改善。对于那些可能不适合神经外科和放射外科治疗的小、出血、深部、单一深部引流的动静脉畸形，静脉内血管内治疗可能是一种考虑因素。
