An accessory hepatic artery is one which arises from an anomalous origin and supplies a portion of the liver along with another artery. A replaced hepatic artery is one which arises from an anomalous origin and supplies a portion of the liver solely.
What is the most common hepatic artery variant?
Type III In the literature, the most frequently encountered variation is Type III, present in between 6% and 15.5% of all cases [12, 13]. The second most frequent variation, Type II, was reported in 2.5–10% of all cases [13, 14]. In our study too, Types III and II were the most commonly seen hepatic arterial variations.
Where is the left gastric artery?

The hepatic artery proper runs anteromedial to the portal vein and medial to the common bile duct to form the portal triad within the hepatoduodenal ligament 1. It terminates by bifurcating into the right and left hepatic arteries before entering the porta hepatis of the liver.
Where does hepatic artery come from?
The common hepatic artery typically originates from the celiac axis together with the splenic and left gastric arteries. After giving off the gastroduodenal artery, the proper hepatic artery bifurcates into the right and left hepatic arteries, which further branch to supply the hepatic segments.

The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine. The inferior pancreaticoduodenal artery arises from the SMA and, along with the superior pancreaticoduodenal artery, supplies the head of the pancreas.
How common is replaced right hepatic artery?
The right hepatic artery arises from the superior mesenteric artery (SMA), also referred to as replaced to the SMA, in 9 to 15% of the population. It is the most common variant in hepatic arterial anatomy.
Which part of the liver does the middle branch of the the left hepatic artery supply?
Gross anatomy The left hepatic artery runs vertically towards the umbilical fissure and supplies segments 1, 2 and 3. It usually gives off a middle hepatic artery branch that runs towards the right side of the umbilical fissure and supplies segments 4a and 4b 2.
What is Porta in human body?
The porta hepatis is a deep fissure in the inferior surface of the liver through which all the neurovascular structures (except hepatic veins) and hepatic ducts enter or leave the liver 1. It runs in the hepatoduodenal ligament and contains: … portal vein (posterior to both)
Where is the superior mesenteric artery?
duodenum The superior mesenteric artery is the artery to the midgut. It supplies the gut from the ampulla of Vater of the 2nd part of the duodenum to the distal third of the transverse colon, and includes structures in between such as 5: jejunum.
What organ is supply by the left gastric artery?

What delivers blood to the left gastric artery?
The vascular supply of the stomach is derived from the celiac artery, which branches into the hepatic artery, left gastric artery, and splenic artery.
Is the left gastric artery and end artery?

The common hepatic artery is one of the final branches of the celiac artery. It supplies oxygen-rich blood to the liver, pylorus, pancreas, and duodenum.
Is common hepatic artery and hepatic artery same?
The hepatic artery proper, also known as the proper hepatic artery (PHA), is the continuation of the common hepatic artery after it gives off the gastroduodenal artery. Just prior to the porta hepatis it divides into the left and right hepatic arteries.
How many hepatic arteries are there?
It subsequently bifurcates into the right and left hepatic arteries. Of note, the right and left hepatic arteries may demonstrate variant anatomy. A misplaced right hepatic artery may arise from the superior mesenteric artery (SMA) and a misplaced left hepatic artery may arise from the left gastric artery.
What is the function of hepatic artery?
The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder.
What is the function of hepatic artery in the liver?
hepatic arteries: A blood vessel that supplies oxygenated blood to the liver.
Is the hepatic artery connected to the heart?
The three main hepatic veins link up at the top of your liver at the inferior vena cava, a large vein that drains the liver to your right heart chamber. On the bottom end of the liver are the organ’s unusual double blood supplies. One is the hepatic artery, which brings in oxygen-rich blood from the heart.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
