A 50-year-old woman with a long-standing history of chronic pancreatitis and hepatitis secondary to alcohol abuse develops acute abdominal pain and comes to the emergency department. As part of her workup, she has a CT scan of the abdomen and pelvis that demonstrates a ruptured splenic artery aneurysm, measuring 4 x 6 cm, and a large amount of free, intraperitoneal hemorrhage. She undergoes emergent, catheter-directed embolization of her splenic artery, which results in occlusion of the left gastro-epiploic artery, which arises from the splenic artery. Collateral flow through which of the following vessels will prevent infarction of the stomach?
A. Omental artery
B. Proper hepatic artery
C. Right colic artery
D. Right gastro-epiploic artery
E. Superior pancreatico-duodenal artery

it can be B from where gastroduodenal artery arises.and then rt.gastroediploic and superior pancreaticoduodenal artery.

you were right before steady....although this is very confusing topic...too many arteries to deal with...

answer is D. There are rich anastomoses between the mesenteric vessels in several areas, including the stomach. The distal right gastro-epiploic artery combines with the distal left gastroepiploic artery to supply the entire greater curve of the stomach. Occlusion of the proximal left gastroepiploic artery will result in reversed flow in the distal artery, which is supplied from the right side.
