A new type of spinal AVM is reported. The characteristics are as follows: All the patients are male over 50-years-old. Their symptoms are insiduous and progressive ischemic pattern. All the lesions locate at the thoracic and lumbar levels. Selective intercostal angiography shows a fistulous AVM adjacent to the intervertebral foramen fed by spinal dural branch and drain into tortuous veins on the spinal cord via radiculomedullary vein. No typical hair-pin configuration by radiculomedullary and spinal cord arteries contributes to the AVM. This type of spinal AVM must be distinguished from so-called singled coiled type spinal cord AVM since pathophysiological features presumably are different from each other; the former is "dural" on anatomical basis, whereas the latter is "pial". Embolization should be recommended as a first choice of treatment to spinal dural AVM.
报道了一种新型的脊髓动静脉畸形（AVM）。其特征如下：所有患者均为50岁以上男性。症状隐匿且呈进行性缺血模式。所有病变均位于胸段和腰段。选择性肋间血管造影显示，椎间孔附近有一个瘘管型AVM，由脊髓硬膜分支供血，并通过根髓静脉引流至脊髓上的迂曲静脉。神经根髓和脊髓动脉无典型的发夹样构型参与AVM。这种类型的脊髓AVM必须与所谓的单盘绕型脊髓AVM相区分，因为其病理生理特征可能彼此不同；前者在解剖学基础上是“硬膜性”的，而后者是“软膜性”的。对于脊髓硬膜AVM，应推荐栓塞作为首选治疗方法。
