A 24-year-old asymptomatic women presented with a large posterior mediastinal mass and a vertebral defect. Cardiac enlargement was found at roentgenographic and echocardiographic investigation. The ECG was abnormal and right heart catheterization showed cardiac output 17.1 l/min with a large left-to-right shunt at the level of the right atrium and the superior caval vein. The mass was seen on angiograms to be fed by numerous vessels originating from the descending aorta between the aortic arch and the coeliac axis. Computed tomography demonstrated a homogeneous, highly vascular structure. Radical excision was successfully accomplished in a two-step procedure aided by partial cardiopulmonary bypass. This seems to be the first report of a macrofistulous arteriovenous malformation in the mediastinum.
一名24岁无症状女性因后纵隔巨大肿块和椎体缺损前来就诊。X线和超声心动图检查发现心脏增大。心电图异常，右心导管检查显示心输出量为17.1升/分钟，在右心房和上腔静脉水平存在大量左向右分流。血管造影显示该肿块由发自主动脉弓与腹腔动脉轴之间降主动脉的众多血管供血。计算机断层扫描显示为均匀的、血管丰富的结构。在部分体外循环辅助下，分两步成功完成了根治性切除。这似乎是纵隔巨大瘘管型动静脉畸形的首例报告。
