In human anatomy, the internal thoracic vein (previously known as the internal mammary vein) is a vessel that drains the chest wall and breasts. Bilaterally, it arises from the superior epigastric vein, accompanies the internal thoracic artery along its course and terminates in the brachiocephalic vein.Click to see full answer. Beside this, where does the internal thoracic artery come from?Structure. The internal thoracic artery arises from the subclavian artery near its origin. It travels downward on the inside of the ribcage, approximately a centimeter from the sides of the sternum, and thus medial to the nipple. It is accompanied by the internal thoracic vein.Additionally, where does the brachiocephalic vein drain into? The right brachiocephalic vein joins the left brachiocephalic vein and forms the superior vena cava. Intercostal veins on the right form an ascending posterior paraspinal vein that drains into the azygos vein, which drains into the superior vena cava prior to its insertion in the right atrium. Likewise, where do intercostal veins drain? The intercostal veins are a group of veins which drain the area between the ribs (“costae”), called the intercostal space. Posterior intercost veins that drain into the Superior intercostal vein – 2nd, 3rd, and 4th intercostal spaces. The superior intercostal vein then drains into the Azygous vein.Where is the left internal mammary artery located?Its location on the left side of the body allows grafting to the LAD without producing tension on the vessel. The LIMA is also closer in size, compared to a vein, to the coronary arteries to which it is anastomosed.
