Gastroduodenal artery This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Gastroduodenal_artery".
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen.
It supplies blood to the pylorus (distal part of the stomach) and the proximal part of the duodenum.
It arises from the common hepatic artery and terminates in a bifurcation, when it splits into the right gastroepiploic artery and the anterior superior pancreaticoduodenal artery.
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.
left gastric: esophageal branches
splenic: pancreatic branches (greater, dorsal) – short gastric – left gastro-omental
common hepatic: proper hepatic (cystic), right gastric, gastroduodenal (right gastro-omental, superior pancreaticoduodenal, supraduodenal)
inferior pancreaticoduodenal – intestinal (jejunal, ileal, arcades, vasa recta) – ileocolic (colic, anterior cecal, posterior cecal, ileal branch, appendicular) – right colic – middle colic
left colic – sigmoid – superior rectal – marginal
visceral: middle suprarenal – renal (inferior suprarenal, ureteral) – gonadal (testicular ♂ / ovarian ♀) parietal: inferior phrenic (superior suprarenal) – lumbar – median sacral terminal: common iliac (IIA, EIA)
umbilical (superior vesical, to ductus deferens) – middle rectal – obturator (anterior branch, posterior branch) – inferior gluteal (accompanying of ischiadic nerve, crucial anastomosis)
uterine ♀ (helicine, vaginal of uterine, ovarian of uterine, tubal of uterine) – vaginal ♀ / inferior vesical ♂
internal pudendal: inferior rectal – perineal (urethral) – posterior scrotal ♂ / labial ♀ – bulb of penis ♂ / vestibule ♀ – deep artery of the penis ♂ (helicine) / clitoris ♀ – dorsal of the penis ♂ / clitoris ♀
iliolumbar (lumbar, iliac) – lateral sacral – superior gluteal
inferior epigastric (cremasteric, round ligament) – deep circumflex iliac – femoral
