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.
The internal thoracic artery is the cardiac surgeon's blood vessel of choice for coronary artery bypass grafting. The left ITA has a superior long-term patency to saphenous vein grafts [6] [7] and other arterial grafts [8] (e.g. radial artery, gastroepiploic artery) when grafted to the left anterior descending coronary artery, generally the ...
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. [1]: 225 It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold (which represents the lateral border of Hesselbach's triangle, the area through which direct inguinal hernias protrude. [2])
The left aortic intercostals run backward on the sides of the vertebrae and are covered by the left lung and pleura; the upper two vessels are crossed by the left superior intercostal vein, the lower vessels by the hemiazygos vein. The sympathetic trunk (opposite the heads of the ribs) and splanchnic nerves pass anterior to the arteries.
The rectus abdominis has many sources of arterial blood supply. Classification of the vascular anatomy of muscles: First, the inferior epigastric artery and vein (or veins) run superiorly on the posterior surface of the rectus abdominis, enter the rectus fascia at the arcuate line, and serve the lower part of
Bilaterally, the internal thoracic vein arises from the superior epigastric vein, and accompanies the internal thoracic artery along its course. [1] It drains the intercostal veins, although the posterior drainage is often handled by the azygous veins. [1] It terminates in the brachiocephalic vein. [2] It has a width of 2-3 mm. [3]
In human anatomy, the superior epigastric veins are two or more [1] venae comitantes which accompany either superior epigastric artery before emptying into the internal thoracic vein. They participate in the drainage of the superior surface of the diaphragm .
The deep circumflex iliac artery arises from the lateral aspect of the external iliac artery nearly opposite the origin of the inferior epigastric artery.. It ascends obliquely and laterally, posterior to the inguinal ligament, contained in a fibrous sheath formed by the junction of the transversalis fascia and iliac fascia.
