Congenital anomalies of the inferior vena cava (IVC) result from complex embryological development and can include rare variations such as duplication of the IVC and interruption of the retro hepatic segment with azygos continuation. We present a case of a double IVC associated with agenesis of the retro hepatic segment and azygos continuation. Although these anomalies are generally asymptomatic, they can predispose to the occurrence of deep vein thrombosis. Modern imaging, particularly computed tomography (CT), plays a crucial role in their detection and characterization. A thorough understanding of these variations is essential for adapting clinical management and avoiding complications during surgical interventions or endovascular procedures.
下腔静脉（IVC）先天性异常源于复杂的胚胎发育过程，可包括一些罕见的变异情况，如下腔静脉重复畸形以及肝后段中断并奇静脉延续。我们报告一例双下腔静脉合并肝后段缺如及奇静脉延续的病例。尽管这些异常通常无症状，但它们可能易引发深静脉血栓形成。现代影像学检查，尤其是计算机断层扫描（CT），在其检测和特征描述中起着关键作用。全面了解这些变异对于调整临床管理以及避免手术干预或血管内操作过程中的并发症至关重要。
