Rare case of concomitant juxtarenal aortic aneurysm and type 1 Inferior Vena Cava duplication: -intraoperative challenges to avoid catastrophe

Abstract

Abstract Duplication of the inferior vena cava is a rare congenital anomaly, with an incidence of 0.2-3%. Despite being asymptomatic, anomalies of IVC are important in aortoiliac and retroperitoneal surgeries. Preoperative CT imaging is essential to identify any IVC anomaly and to prevent unexpected hemorrhage during surgery. Here, we report a case of a juxtarenal abdominal aortic aneurysm in which we encountered a type I IVC duplication anomaly intraoperatively while performing transperitoneal aneurysmorrhaphy and took precautions to avoid any iatrogenic injuries to either of the two trunks or the pre-aortic trunk of the anomalous duplicate IVC.
