Illustration of findings of double IVC. Note that the right renal vein (RRV) and left renal vein (LRV) drain to the right inferior vena cava (RIVC) and the left inferior vena cava (LIVC), respectively. The continuous hemiazygos vein (CHA) joins the continuous azygos vein (CA) suprediaphragmatically. Ascending lumbar veins drain to the CA and the CHA (deep collateral pathway). (RA: right atrium; A: aorta; SVC: superior vena cava; CIV: common iliac vein; D: diaphragm)
