The angiographic findings of 10 cases with azygos (AC) or hemiazygos (HC) continuation of the inferior vena cava (IVC), associated with other congenital heart disease (0.5%), are described. Abdominal situs solitus was present in 7 cases, left isomerism in 3. In 5 cases IVC was to the left to the spine, bilateral in one. In 6 cases there was AC, HC in 2; in one both types of continuation were documented. It is important that this venous anomaly be diagnosed before cardiac catheterization; manipulation of the probe may be very difficult when saphenous approach is used. The correct use of the terms "Azygos", "Hemiazygos" and "Accessory Hemiazygos" are discussed.
描述了10例下腔静脉奇静脉延续（AC）或半奇静脉延续（HC）并伴有其他先天性心脏病（0.5%）患者的血管造影结果。7例为正常腹部脏器位置，3例为左位异构。5例下腔静脉位于脊柱左侧，1例双侧均有。6例为奇静脉延续，2例为半奇静脉延续；1例记录了两种延续类型。在心脏导管插入术前诊断这种静脉异常很重要；当使用大隐静脉入路时，探头操作可能非常困难。文中还讨论了“奇静脉”“半奇静脉”和“副半奇静脉”这些术语的正确用法。
