Infrarenal abdominal aortic aneurysm and left-sided inferior vena cava. (a) Computed tomography revealed that the inferior vena cava ran left to the abdominal aortic aneurysm (AAA). The AAA was 50 mm in diameter. (b) The left-sided inferior vena cava crossed the aortic neck anteriorly after receiving the left renal vein at the level of the bilateral renal arteries and ran right to the aorta in the normal position.

The left gonadal and adrenal veins were direct tributaries of the LIVC (Figure 1).
Surgical view of the abdominal aortic aneurysm and left-sided inferior vena cava. (a) After mobilizing the duodenum, right colon, and intestine by employing the Cattell-Braasch maneuver, the aorta was clearly observed from the neck of the abdominal aortic aneurysm (AAA) to both of the common iliac arteries. (b) A bifurcated artificial graft was implanted from the infrarenal aorta to the bilateral common iliac arteries. Arrows indicate the left-sided inferior vena cava. Arrowheads indicate the neck of the AAA.

The bilateral common iliac arteries were also dissected for clamping in the surgical field (Figure 2). KG, Germany) was implanted from the infrarenal aorta to the bilateral common iliac arteries (Figure 2).
