Ruptured Abdominal Aortic Aneurysm with Double Inferior Vena Cava

Abstract

A 60-year-old man was referred to our hospital because of sudden onset of back pain and numbness of his lower limbs, associated with loss of consciousness. Computed tomography (CT) showed a ruptured juxtarenal abdominal aortic aneurysm (AAA) and a double inferior vena cava (IVC), and an emergency operation was performed. Intraoperatively, the aortic clamp was placed above the left renal artery and the abdominal aortic aneurysm was repaired with a woven straight graft. Although the left IVC crossed over the neck of the AAA anteriorly, we could perform a proximal anastomosis to retract the IVC in either a cephalad or caudad direction without injuring the vein. The patient was discharged from hospital on the 20th postoperative day. We report a case of ruptured AAA with a double IVC.
