We describe spontaneous disappearance of an aneurysmal malformation of the vein of Galen (AMG), an anomaly that occurs most often in children, with a high mortality due to the accompanying severe cardiac failure. Spontaneous thrombosis of an AMG is rare. In this case, the AMG has been closed for about 5 years, without radiological evidence of thrombosis, and no active treatment. Proposed mechanisms of spontaneous thrombosis include slow flow shunts and severe obstruction of the venous outflow. However, in this case, the disappearance of the AMG without evidence of thrombosis indicates a different mechanisms, namely, obstruction of the feeding artery.
我们描述了大脑大静脉动脉瘤样畸形（AMG）的自发消失，这种异常在儿童中最为常见，由于伴有严重心力衰竭，死亡率很高。AMG的自发血栓形成很少见。在本病例中，AMG已闭合约5年，无血栓形成的影像学证据，且未进行积极治疗。自发血栓形成的推测机制包括缓慢分流和静脉流出道严重梗阻。然而，在本病例中，AMG消失但无血栓形成证据提示了一种不同的机制，即供血动脉梗阻。
