Question

Ligation of the hepatic artery will impair blood supply in

• A. Right gastric and Right gastroepiploic artery
• B. Right gastric and Left gastric artery
• C. Right gastroepiploic and short gastric vessels
• D. Right gastric and short gastric vessels

Answer 1

The Correct Option is A

When the hepatic artery is ligated, it affects the blood supply to the arteries that branch off from it. The hepatic artery is a major source of blood supply to the liver, but it also branches out to supply blood to other structures in the upper abdominal region.

Understanding the branches of the hepatic artery helps us pinpoint which areas are deprived of blood supply when the artery is ligated. The common hepatic artery gives rise to the gastroduodenal artery and the right gastric artery, among other branches.

The gastroduodenal artery further divides into the right gastroepiploic artery and superior pancreaticoduodenal artery. Since the right gastroepiploic artery and the right gastric artery are both branches stemming from the pathways of the hepatic artery, their blood supply will be impaired if the hepatic artery is ligated.

Affected Artery	Source
Right Gastric Artery	Common Hepatic Artery
Right Gastroepiploic Artery	Gastroduodenal Artery (branch of Common Hepatic Artery)

Hence, the ligation of the hepatic artery will impair the blood supply in the "Right gastric and Right gastroepiploic artery."
