脊髓动静脉畸形（AVM）患者由于出血、静脉高压、血管盗血现象或静脉曲张引起的占位效应而具有进行性或波动性神经功能障碍。根据血管造影和手术结果，将脊髓AVM分为四种类型。常规诊断方法包括磁共振成像（MRI）、仰卧位脊髓造影和血管造影。MRI可以定位脊髓内的血管病灶，但有时可能是正常的。脊髓血管造影是明确的诊断方法。它在技术上要求很高且耗时，需要对所有脊髓血管蒂进行导管插入。磁共振血管造影是快速和多平面的，它可以通过显示供血动脉的水平来缩短导管血管造影的时间。磁振造影、磁振造影及导管血管造影的影像，以说明脊髓动静脉畸形的相关性及诊断。(C)2004年爱思唯尔公司All rights reserved.
Patients with spinal arteriovenous malformation (AVM) have progressive or fluctuating neurological dysfunction because of hemorrhage, venous hypertension, vascular steal phenomenon, or mass effect from venous varicosity. Spinal AVM is classified into four types based on angiographic and operative findings. Conventional diagnostic methods include magnetic resonance imaging (MRI), supine myelogram, and angiogram. MRI can localize the vascular nidus in the cord, but it may sometimes be normal. Spinal angiogram is the definitive diagnostic modality. It is technically demanding and time consuming, requiring catheterization of all spinal vascular pedicles. MR angiography is fast and multiplanar, and it may shorten the duration of catheter angiography by demonstrating the level of feeders. Images of MRI, magnetic resonance angiography (MRA), and catheter angiogram are presented to illustrate the correlation and diagnosis of spinal AVM. (C) 2004 Elsevier Inc. All rights reserved.
