Two patients diagnosed with arteriovenous malformation (AVM) in close association with a developmental venous anomaly (DVA) are reported. The first patient presented with episodes of left extremity weakness and numbness as well as chronic headaches. The second patient presented with spontaneous intracerebral hemorrhage. Cerebral angiography showed that both the AVM and the transmedullary veins of the DVA drained through the transcortical vein. The AVMs were treated by highly selective transarterial embolization with Onyx embolic agent while preserving the DVAs. It is suggested that the cause of the presentation in both patients was secondary to the association of the AVM with the delicate hemodynamic balance and less robust angioarchitecture of the DVA.
现报道 2 例与发育性静脉异常（DVA）密切相关的动静脉畸形（AVM）患者。第 1 例患者表现为左肢无力和麻木以及慢性头痛。第 2 例患者表现为自发性脑出血。脑血管造影显示 AVM 和 DVA 的穿髓静脉均通过皮质静脉引流。使用 Onyx 栓塞剂对 AVM 进行高度选择性经动脉栓塞治疗，同时保留 DVA。这表明，2 例患者的表现原因是 AVM 与 DVA 的脆弱血流动力学平衡和不那么稳健的血管结构之间的关联。
