 note = {application/pdf, Summary We encountered a case of double inferior vena cava (DIVC) in a 76 year old male cadaver during anatomy practice at Matsumoto Dental University in 2015. The left and right internal iliac veins drained into the interiliac vein ran horizontal in front of the cape angle and joined the left and right external iliac veins. Then the inferior vena cava on each side originated.The width of the origin of the inferior vena cava were 13.7 mm and 11.6 mm on the right and left side, respectively. Based on the previous DIVCʼs classifications, we attempted to classify the DIVC and iliac venous system by combining the direction of the internal iliac veins (lateral (l), vertical (s), and medial (m)), the inclination of the interiliac veins (lower left to upper right (L to R), horizontal (H), and lower right to upper left (R to L)),and the width of the right and left IVC (RIVC>LIVC, RIVC=LIVC, and RIVC<LIVC), to the present and the 53 cases of the DIVC in literature from 1901 to 2022. According to the classification, the present case was classified RIVC>LIVC, H, l-l. In this case, hemi-azygos vein was not found, and the height of the left kidney was lower than the right one. We therefore investigated the co-existence of the venous system and the height of the kidney to the 53 cases and referred to the embryological relationship between them. The present classification provides basic knowledge for the clinical anatomy and surgery of the pelvic region.},
