In human anatomy , the superior epigastric artery is a terminal[1] 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 [ edit ]
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 [ edit ]
The superior epigastric artery pierces the diaphragm [1] 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 .[citation needed
Anastomoses [ edit ]
It anastomoses with the inferior epigastric artery [4] [2] [4] [1] umbilicus .[2]
Distribution [ edit ]
Where it anastomoses, the superior epigastric artery supplies the anterior part of the abdominal wall,[5] [6] [5] diaphragm .[citation needed
Collateralization in disease [ edit ]
Vascular disease [ edit ]
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 [ edit ]
A congenitally narrowed aorta, due to coarctation , is often associated with a significant enlargement of the internal thoracic and epigastric arteries.[8]
