Left-sided Inferior Vena Cava and Aortoiliac Surgery

Congenital anomalies of the inferior vena cava vein are rare but may cause serious complications during abdominal aortic surgery. We present two patients with left-sided inferior vena cava: one with an abdominal aortic aneurysm and another with aortoiliac occlusive disease. The preoperative detection of such anomalies helps with operative planning, facilitates the surgical technique and may reduce the risk of severe venous haemorrhage.
