ABDOMINAL AORTA – Abdominal aortic aneurysm (AAA)

The aorta from the inferior mesenteric artery to just beyond the bifurcation is seen. Beginning just below the level of the renal arteries, the aorta is swollen in a fusiform fashion. The posterior surface has been dissected with some difficulty from the anterior surface of the vertebral column. On the posterior surface the atherosclerotic media can be seen. The swelling has been sufficient to distort the angle at which the common iliac vessels arise.
