Double inferior vena cava is a congenital venous anomaly that is found at about 1% to 3% of routine autopsies and has been described in numerous reports over the years. According to Adachi (1940), it has an incidence of 1.4±0.34%. More recently, diagnostic imaging has revealed that double inferior vena cava tends to be found in patients with hydronephrosis and various other conditions. During routine anatomical practice at Nippon Medical School in 2000, a case of double inferior vena cava was observed in a Japanese woman who had died of subarachnoid hemorrhage at 66 years of age. Bilateral inferior venae cavae, left renal vein, and transiliac vein were found through dissection. These findings are supplemented by a discussion of the literature with respect to embryological studies, morphological classifications, and disease correlations.
