Gastroduodenal artery (Arteria gastroduodenalis)
Educational content only — not medical advice.
Anatomy
Arises from the common hepatic artery and descends posterior to the first part of the duodenum, bifurcating into the superior pancreaticoduodenal and right gastro-omental arteries.
Clinical notes
Lies directly behind the posterior wall of the duodenal bulb; posterior peptic ulcer penetration into the GDA causes catastrophic arterial GI bleeding requiring transcatheter embolization.
