Abstract: The inferior vena cava (IVC) is the principal venous duct of the lower body, extending as a single vessel along the right side of the abdominal aorta and terminating in the right atrium.Double IVC is a rare anomaly that is typically detected incidentally during imaging or retroperitoneal surgery.In a cadaver of an elderly Chinese male, we observed a double IVC in which the right and left IVCs were parallel on both sides of the abdominal aorta.The left IVC eventually converges with the left renal vein, which subsequently crosses the abdominal aorta anteriorly to merge with the right IVC, returns to a single normal IVC, passes through the diaphragm, and terminates in the right atrium.No other apparent anomalies were present, except for two right testicular veins, the smaller of which drained into the right IVC and the larger drained into the right renal vein.Although individuals with anomalous IVC are typically asymptomatic, care must be taken to avoid errors during radiological imaging and retroperitoneal surgery.In such cases, a preoperative understanding of multiple anomalous vessels will help physicians to avoid potential risks during abdominal and retroperitoneal surgeries.
