The posterior thoracic wall, an area drained by the azygos venous system, is a common site for surgical intervention. Since the venous part of the cardiovascular system is subject to most common variation, abnormalities in the azygos venous system are often reported.
During routine dissection classes for undergraduate medical students, we encountered a variation in the azygos venous system in a 65 years old south Indian male cadaver. We observed that there was no accessory azygos vein, and left 4th, 5th, 6th and 7th posterior intercostal veins terminated directly into azygos vein.
Identifying these types of variations is important during imaging this region and surgical operations of mediastinum.
胸后壁是奇静脉系统引流的区域，是外科手术干预的常见部位。由于心血管系统的静脉部分变异最为常见，奇静脉系统的异常情况经常被报道。
在为本科医学生进行的常规解剖课上，我们在一名65岁的南印度男性尸体中发现了奇静脉系统的变异。我们观察到没有副奇静脉，左第4、5、6和7后肋间静脉直接汇入奇静脉。
在对该区域进行成像和纵隔手术时，识别这些类型的变异很重要。
