Blood vessel
In
human anatomy , the superior epigastric artery is a terminal
[1] branch of the
internal thoracic artery that provides arterial supply to the
abdominal wall , and upper
rectus abdominis muscle . It enters the
rectus sheath to descend upon the inner surface of the
rectus abdominis muscle . It ends by
anastomosing with the
inferior epigastric artery .
Structure
Origin
The superior epigastric artery arises from the
internal thoracic artery (referred to as the
internal mammary artery in the accompanying diagram).
[2]
[3]
Course and relations
The superior epigastric artery pierces the
diaphragm
[1] to enter the
rectus sheath and descend upon the deep surface of the
rectus abdominis .
[4]
Along its course, it is accompanied by a similarly named
vein , the
superior epigastric vein .[

Anastomoses
It
anastomoses with the
inferior epigastric artery
[4]
[2] within the rectus abdominis muscle
[4]
[1] at the
umbilicus .
[2]
Distribution
Where it anastomoses, the superior epigastric artery supplies the anterior part of the abdominal wall,
[5]
[6] upper rectus abdominis muscle,
[5] and some of the
diaphragm .[

Collateralization in disease
Vascular disease
The superior epigastric arteries,
inferior epigastric arteries ,
internal thoracic arteries and left
subclavian artery and right subclavian artery /
brachiocephalic are
collateral vessels to the
thoracic aorta and
abdominal aorta . If the abdominal aorta develops a significant
stenosis and/or blockage (as may be caused by
atherosclerosis ), this collateral pathway may develop sufficiently, over time, to supply blood to the
lower limbs .
[7]
Coarctation of the aorta
A congenitally narrowed aorta, due to
coarctation , is often associated with a significant enlargement of the internal thoracic and epigastric arteries.
