Double Inferior Vena Cava with Azygos Continuation and Retroaortic Left Renal Vein Associated with Juxtarenal Abdominal Aortic Aneurysm Surgery

The combination of a double inferior vena cava (IVC), a retroaortic left renal vein, and azygos continuation of the IVC is extremely rare. Here we report the case of a 74-year-old man with this complex venous anomaly associated with a juxtarenal abdominal aortic aneurysm (AAA), who underwent a succe...

Sumario:The combination of a double inferior vena cava (IVC), a retroaortic left renal vein, and azygos continuation of the IVC is extremely rare. Here we report the case of a 74-year-old man with this complex venous anomaly associated with a juxtarenal abdominal aortic aneurysm (AAA), who underwent a successful graft implantation with left renal artery reconstruction without injuring the retroaortic venous system. The venous anomaly was diagnosed using preoperative contrast-enhanced computed tomography (CT). Thus, contrast-enhanced CT can provide sufficient information on AAA and anomalous venous anatomy to avoid fatal complications during AAA surgery.
