Middle Colic Artery Originating from the Gastroduodenal Artery Discovered during a Whipple

Figure 2

Middle colic artery arising from the gastroduodenal artery. Intraoperative photographs. 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. (a) The aberrant middle colic artery can be seen running into the transverse colon mesentery (transverse colon seen in the bottom left corner). (b) The aberrant middle colic is seen crossing on top of the pancreatic neck. The common bile duct is transected, and the bull dog clamp is on the proximal common bile duct.
