Abdomen Arteries

Schematic drawing of the thoracic and abdominal aorta and branches

Right: Late-phase aortography showing the bilateral nephrogram and contrast enhancement of the adrenal glands.

Schematic drawing of the celiac trunk, showing the hepatic arteries, segments (Couinaud), and the gastric and splenic circulation. Based on a real angiogram.

Left: Selective angiogram of the celiac trunk, showing the hepatic circulation, and the gastric, pancreatic, and splenic circulation. The pattern presented here is the most common and present in about 40% to 50% of the population.

Right: Late phase of the angiogram showing the splenic and portal veins, as well as the splenic blush and the hepatic blush.

Schematic drawing showing the arterial circulation of the duodenum, stomach, spleen, and greater omentum, as well as the anastomotic collaterals.

Selective injection at the celiac trunk with a normal distribution of the branches. Note the dorsal pancreatic artery arising from the bifurcation of the celiac artery and that most of the arterial circulation of the pancreas arises from the dorsal pancreatic artery. Only one major artery in the head of the pancrease is visualized.

Schematic drawing of the hepatic segments according to the Couinaud description, showing the portal vein distribution, the hepatic lobar division, and hepatic fissures.
