Anatomy and function of the supraduodenal artery


Supraduodenal artery[edit | edit source]

The supraduodenal artery is a small artery that supplies blood to the duodenum, which is the first section of the small intestine. It is an important vessel in the circulatory system of the gastrointestinal tract.

Anatomy[edit | edit source]

The supraduodenal artery typically arises from the gastroduodenal artery, which is a branch of the common hepatic artery. The common hepatic artery is one of the three branches of the celiac trunk, a major artery that supplies blood to the upper abdominal organs.

The supraduodenal artery courses along the superior aspect of the duodenum, providing arterial blood supply to this region. It is often found in the vicinity of the first part of the duodenum, also known as the superior duodenum.

Function[edit | edit source]

The primary function of the supraduodenal artery is to supply oxygenated blood to the duodenum. This is crucial for the proper functioning of the duodenum, which plays a key role in the digestion and absorption of nutrients.

Clinical significance[edit | edit source]

The supraduodenal artery, although small, can be of clinical significance in certain surgical procedures involving the duodenum or the pancreas. Its location and course must be considered to avoid inadvertent injury during surgeries such as pancreaticoduodenectomy (Whipple procedure).
