Supraduodenal artery

Right hepatic angiogram - Injection of 2 cc/s for 10-12 cc. Vessels of interest include the middle hepatic artery, supraduodenal artery, and cystic artery. Rarely, the right hepatic artery may arise directly from the aorta. 

The pancreatoduodenal arcade provides an extensive collateral vascular network to the head of the pancreas, uncinate process, and duodenal bulb with a complex anatomical disposition and anastomotic channels with named arteries such as the dorsal pancreatic artery, the supraduodenal artery, and the retroduodenal artery [8-13]. 

The supraduodenal artery (of Wilkie) [14] is a small artery that supplies blood to the anterior and posterior surfaces and upper portion of the duodenum and pylorus, and communicates with the pancreatoduodenal arcade, as well as right gastric branches. It is reported to be present in 93% of patients, with a high degree of variation in its origin, the most frequent being the gastroduode-...

Supraduodenal artery - This vessel provides blood supply to the upper portion of the duodenum and pylorus [2]. The origin of this vessel is also variable, and it communicates with the pancreaticoduodenal arcade as well as right gastric branches [7]. If identified, this vessel should be prophylactically embolized. 

Selective right hepatic arteriogram-injection of 3 cc/sec for 12 cc. Normally, the right hepatic artery provides flow to segments 1 (caudate lobe may have other blood supply), 5,6,7, and 8. Particular attention should be paid to the supraduodenal, retro-duodenal, retroportal and cystic arteries.
