What is mammary branch?

Right internal thoracic artery and its branches (labeled under its old name the Internal mammary artery, at upper right.) It is a paired artery, with one running along each side of the sternum, to continue after its bifurcation as the superior epigastric and musculophrenic arteries.

What does internal mammary artery supply?

The internal thoracic artery, aka the internal mammary artery, supplies the breast and the anterior chest wall. The internal thoracic artery travels along the inner surface of the anterior chest wall on both sides. The internal thoracic artery runs under the fascia and deep to the intercostal muscles.

Where does the internal mammary artery come from?

The IMAP flaps, as the name implies, derive from the internal mammary artery (IMA). The IMA originates from the subclavian artery and travels along the sternal border on each side of the sternum. It becomes the superior epigastric artery in the upper abdomen and nourishes the upper part of the rectus abdominis muscle.

What muscle does the internal thoracic artery pass anterior to?

internal intercostal muscles
They have a short medial course along the inner surface of the superior six intercostal spaces. Accompanied by the cutaneous branches of the intercostal nerves, these arteries pierce through the internal intercostal muscles and emerge on the anterior surface of the thoracic cage.

Where does breast carcinoma most commonly occur?

Typically, the cancer forms in either the lobules or the ducts of the breast. Lobules are the glands that produce milk, and ducts are the pathways that bring the milk from the glands to the nipple. Cancer can also occur in the fatty tissue or the fibrous connective tissue within your breast.

What arteries supply the breast?

The main sources of blood supply to the breast are described in textbooks as the internal thoracic, lateral thoracic, and posterior intercostal arteries.

How long does a mammary artery bypass last?

Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg (saphenous vein), inside your chest (internal mammary artery), or your arm (radial artery).

Why is the internal mammary artery used during bypass surgery?

The internal mammary artery (IMA) grafts have been associated with long-term patency and improved survival as compared to saphenous vein grafts (SVGs). Early failure of IMA is attributed to poor surgical technique and less with thrombosis.

What are the branches of descending aorta?

As it descends in the thorax, the aorta gives off several paired branches. In descending order these are the bronchial arteries, the mediastinal arteries, the esophageal arteries, the pericardial arteries, and the superior phrenic artery.

Are there two internal thoracic veins?

Bifurcation of each internal thoracic vein is common. The left internal thoracic vein may bifurcate between ribs 3-4 or remain as a single vein. The right internal thoracic vein may bifurcate between ribs 2-4 or remain as a single vein.

What is the anatomy of the internal thoracic artery?

Internal thoracic artery 1 Gross anatomy. The internal thoracic artery arises from the first part of the subclavian artery in the base of the neck. 2 Supply. The internal thoracic artery supplies the anterior body wall from clavicle to umbilicus including the sternum and the breasts. 3 Variant anatomy

Which is artery irrigated by the inferior wall?

Inferior wall: irrigated by the posterior interventricular artery, a branch of the right coronary artery (RCA) in 85% of the people or the circumflex artery in 15%. With these data it is easy to determine which artery is causing a myocardial infarction anterior, septal and even side.

Is the ITA an artery in the chest wall?

[edit on Wikidata] In human anatomy, the internal thoracic artery (ITA), previously known as the internal mammary artery (a name still common among surgeons), is an artery that supplies the anterior chest wall and the breasts.

How is the thoracic artery accompanied by venae comitantes?

The artery is accompanied by venae comitantes that coalesce at the third costal cartilage to form a single internal intercostal vein that travels medial to the artery. There is also a lymphatic chain that accompanies the vessels along their course. The internal thoracic artery gives off five sets of branches :
