The azygos venous system in the posterior mediastinum has a complex developmental pattern.
During the dissection of this region, we encountered a variation in this system. In this case, we observed that the accessory hemiazygos and hemiazygos veins in the left side passed anterior to the aorta and drained to the azygos vein located on the left side of the vertebral column. Other structures were normal in this area.
This variation is important in mediastinal surgery and radiographic interpretation.
后纵隔的奇静脉系统具有复杂的发育模式。
在该区域的解剖过程中，我们发现了该系统的一种变异。在这种情况下，我们观察到左侧的副半奇静脉和半奇静脉在主动脉前方通过，并引流到位于脊柱左侧的奇静脉。该区域的其他结构正常。
这种变异在纵隔手术和影像学解释中很重要。
