Abdominal Aortic CT Angiography
Abstract
The abdominal aorta begins at the aortic hiatus of the diaphragm and terminates at the aortic bifurcation to become the iliac arteries. Abdominal aortic branches are divided into three sets: visceral, parietal, and terminal branches. Visceral branches include the celiac artery, the superior mesenteric artery (SMA), the inferior mesenteric artery (IMA), the middle suprarenal arteries, the renal arteries, the internal spermatic arteries, and the ovarian arteries (in females). With the exception of the SMA and IMA, all visceral branches are paired. Parietal branches include the inferior phrenic arteries (paired), the lumbar arteries (paired), and the middle sacral artery. The common iliac arteries make up the terminal branches.
