The hepatic artery proper (also proper hepatic artery) is the artery that supplies the liver and gallbladder. It arises from the common hepatic artery, a branch of the celiac artery.
Structure
[edit]The hepatic artery proper arises from the common hepatic artery and runs alongside the portal vein and the common bile duct to form the portal triad. A branch of the common hepatic artery—the gastroduodenal artery—gives off the small supraduodenal artery to the duodenal bulb. Then the right gastric artery comes off and runs to the left along the lesser curvature of the stomach to meet the left gastric artery, which is a branch of the celiac trunk. The proper hepatic artery subsequently bifurcates into the right and left hepatic arteries.
Variant anatomy
[edit]The right and left hepatic arteries may demonstrate anatomic variation. A replaced right hepatic artery (rRHA) refers to a right hepatic artery that does not originate from the proper hepatic artery, but instead arises aberrantly—most commonly from the superior mesenteric artery (SMA). This variant occurs in approximately 11–21% of individuals and travels posterior to the portal vein and common bile duct, which has important surgical implications.[1]
A replaced left hepatic artery (rLHA) may arise from the left gastric artery and ascend through the lesser omentum toward the liver.[2]
Other origins for variant right hepatic arteries include the proximal or middle common hepatic artery, gastroduodenal artery, splenic artery, celiac axis, or even directly from the abdominal aorta.[3]
The cystic artery most commonly originates from the right hepatic artery—replaced or not—but may also demonstrate variation.[4]
