What does inferior epigastric artery supply?

The inferior epigastric artery (IEA) is a major blood vessel that supplies the anterior abdominal wall. It arises from the external iliac artery, proximal to the inguinal ligament.

What vessel gives rise to the inferior epigastric artery?

The inferior epigastric artery (IEA)arises from the medial side of the external iliac artery and immediately passes to the medial side of the ductus deferens in males or the round ligament in females. The IEA is a major blood vessel that supplies the anterior abdominal wall.

How do you trace an inferior epigastric artery?

It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends between the rectus abdominis muscle and the posterior lamella of …

Where do inferior epigastric arteries come from?

The inferior epigastric artery arises from the external iliac artery and is an important artery supplying the anterior abdominal wall. If a superficial inferior epigastric artery is present, as seen in about two-thirds of cases, then the inferior epigastric artery is referred to as the deep inferior epigastric artery.

Is the epigastric artery a major artery?

The main arterial supply to the abdominal wall comes from the epigastric arteries. The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.

What does the epigastric artery do?

In human anatomy, the superior epigastric artery is a blood vessel that carries oxygenated blood to the abdominal wall, and upper rectus abdominis muscle.

Where is the epigastric vein?

In human anatomy, superior epigastric vein refers to a blood vessel that carries deoxygenated blood and drains into the internal thoracic vein. It anastomoses with the inferior epigastric vein at the level of the umbilicus and drains the anterior part of the abdominal wall and some of the diaphragm.

What is epigastric artery?

What do the epigastric arteries supply?

The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.

What does it mean when your epigastric region hurts?

Most commonly, epigastric pain is the result of overeating, drinking alcohol while eating, or consuming greasy or spicy foods. Epigastric pain can be caused by digestive conditions, such as acid reflux or lactose intolerance. Gastroesophageal reflux disease (GERD) is another possible cause of epigastric pain.

How big is the inferior epigastric artery?

The inferior epigastric artery is a relatively large vessel at its source, with a diameter of 3 to 4 mm. Paired venae comitantes accompany the artery to drain the flap and, in two thirds of cases, join to form a single venous pedicle before entering the external iliac vein. The venous pedicle has a similar diameter to the arterial supply.

Where does the obturator artery and the epigastric artery originate?

This origin of the obturator artery from the epigastric occurs in about 20% of individuals. From Pick, et al. (1942), “The pubic branch of the inferior epigastric anastomoses with the pubic branch of the obturator.

Who was the first doctor to study the inferior epigastric artery?

The inferior epigastric artery was not well understood until Mall (1898; F.P. Mall, an Iowan by birth, Belle Plaine, medically trained in Germany was the first Professor of Anatomy at The Johns Hopkins Medical School) studied its development. This artery has received much attention in the literature because of its relation to femoral hernia.

Where does the hepatic artery and superior epigastric artery meet?

The right artery gives off a small branch that anastomoses with the branches of the hepatic artery near the falciform ligament of the liver Each superior epigastric artery gives off a small branch that passes anterior to the xiphoid process of sternum and anastomoses with the contralateral counterpart.
