[The gastroduodenal artery and its variations. Study of 100 arteriographies].

The gastro-duodenal artery, whose study has been based on a series of one hundred digestive arteriographies, is visualized in all cases. Its variations of origine are directly connected to the different possible dispositions of the hepatic arterial supply. The analysis of the results confirms the literary data: each time there is a middle hepatic artery, it gives the gastro-duodenal artery.
