Middle colic artery arising from the gastroduodenal artery. (a) Intraoperative photograph. One vessel loop is around the neck of the pancreas, and the second vessel loop is encircling the origin of the gastroduodenal artery. The anterior and posterior superior pancreaticoduodenal arteries and smaller unnamed branches off the gastroduodenal artery have been ligated. The common bile duct has already been transected. (b) Illustration of the middle colic artery arising from the gastroduodenal artery as seen during the pancreaticoduodenectomy. RHA: right hepatic artery; LHA: left hepatic artery; LGA: left gastric artery; SMA: superior mesenteric artery; SA: splenic artery; RGEA: right gastroepiploic artery; PSPDA: posterior superior pancreaticoduodenal artery; MCA: middle colic artery; JA: jejunal arteries.
