What is the origin of superior pancreaticoduodenal artery?
Superior pancreaticoduodenal artery is a branch of gastrodudenal artery, a terminal branch of common hepatic artery, which is one of the three branches of Coeliac axis.
Contrast enhanced arterial phase CT scan of upper abdomen demonstrate
- Relatively high origin of the celiac artery which is narrowed just distal to the ostium by the median arcuate ligament of diaphragm.
- The superior and inferior pancreaticoduodenal arteries are quite prominent and tortuous suggesting collateral circulation between SMA and coeliac axis circulation, and show heavy atherosclerotic disease, which is disproportionately severe when compared with aorta and its other branches.
- A saccular aneurysm with calcified walls measuring approximately 20 x 20mm arising from the inferior pancreaticoduodenal artery.
- Heavy atherosclerotic calcifications in the splenic artery and in pancreaticoduodenal arteries. No splenic artery aneurysm is seen. secondary to celiac artery narrowing. , measuring 20 x 20 mm.
- Incidentally, a Bosniak class 2 lesion, bordering class 3.
