We report two cases of interrupted inferior vena cava with azygous continuation diagnosed as an isolated finding during routine prenatal scans. Visualization of the venous vasculature of the abdomen and thorax in the mid-sagittal plane failed to visualize the segment of the inferior vena cava between the kidneys and the liver. A vessel with venous flow was observed parallel, adjacent and posterior to the aorta between the kidney and the right atrium. This blood vessel connected with the superior vena cava. Axial planes of the thorax confirmed the presence of two vessels running paravertebrally. A detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies. The neonatal course of both fetuses was uneventful. Isolated interruption of the inferior uena cava can be a vascular malformation without known pathological consequences.
我们报告两例下腔静脉中断伴奇静脉延续的病例，这是在常规产前扫描中作为孤立发现而诊断出来的。在中矢状面观察腹部和胸部的静脉血管时，未能看到肾与肝之间的下腔静脉段。在肾与右心房之间，观察到一条有静脉血流的血管与主动脉平行、相邻且位于其后方。该血管与上腔静脉相连。胸部的轴向平面证实有两条血管沿脊柱旁走行。对胎儿解剖结构进行的详细超声检查未发现其他异常。两个胎儿的新生儿期过程均顺利。孤立性下腔静脉中断可能是一种血管畸形，尚无已知的病理后果。
