Attempted venous cannulation with a dual-stage cannula for cardiopulmonary bypass in routine coronary revascularization led to the discovery of an abnormal inferior vena cava in a 65-year-old patient. The operative and postoperative course of the patient were not affected by the inferior caval anomaly. The detailed infradiaphragmatic venous anatomy was elucidated later by MRI and showed bilateral inferior caval veins with azygos continuation. Although this malformation of the inferior cava is rare in adults, the occurrence should be known. Quick recognition and handling should be achieved if detected during cannulation for cardiopulmonary bypass.
在常规冠状动脉血运重建术中，使用双阶段插管进行体外循环静脉插管时，发现一名65岁患者的下腔静脉异常。患者的手术及术后过程未受下腔静脉异常的影响。随后通过磁共振成像（MRI）阐明了详细的膈下静脉解剖结构，显示双侧下腔静脉并延续至奇静脉。虽然这种下腔静脉畸形在成年人中很少见，但仍应了解其存在。如果在体外循环插管过程中检测到，应迅速识别并处理。
