Azygos System of Veins and Superior Vena Cava 收藏

Azygos静脉系统和上腔静脉
摘要
The azygos system (Fig. 282) consists of 3 veins which form longitudinal collecting trunks into which the intercostal veins drain: the azygos (vena azygos major), the hemiazygos (vena azygos minor inferior) and the accessory hemiazygos (vena azygos minor superior). The azygos is located on the right side, and the hemiazygos and the accessory hemiazygos on the left. The right and the left ascending lumbar veins constitute the most caudal portion of the system and drain into the azygos and the hemiazygos, respectively. These veins, because they link together the superior and the inferior venae cavae, constitute important anastomosing channels.

azygos系统(图。 282)由3个静脉组成,形成纵向收集的树干,肋间静脉排出:azygos(vena azygos major),hemiazygos(vena azygos minor inferior)和附属hemiazygos(vena azygos minor superior)。 azygos位于右侧,hemiazygos和附件hemiazygos位于左侧。左右上行的腰静脉构成系统的最尾部,分别排入奇数和半合子。这些静脉,因为它们将上腔静脉和下腔静脉连接在一起,构成了重要的吻合通道。
