What does brachiocephalic artery supply?

The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.

Where is brachiocephalic artery?

The brachiocephalic (innominate) artery is a thick-walled blood vessel that originates from the aortic arch, the top part of the aorta—the main vessel that carries blood from the heart. It brings blood to the right carotid artery in your neck and the right subclavian artery, which supplies blood to the right arm.

What is brachiocephalic aneurysm?

Brachiocephalic vein aneurysms are rare lesions with only 36 cases reported in the literature. They usually present incidentally as mediastinal widening on chest X-ray, with thromboembolism or mass effect on adjacent structures, or rupture.

What is the meaning of brachiocephalic?

: a short artery that arises from the arch of the aorta and divides into the carotid and subclavian arteries of the right side. — called also innominate artery.

Is brachiocephalic a vein or artery?

The brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.

What are the 3 branches of the aorta?

The convexity of the aortic arch gives off three branches; the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. Brachiocephalic trunk: also called the brachiocephalic artery, is the first and largest artery that branches off the aortic arch.

Is the brachiocephalic artery or vein?

What is left subclavian artery?

The left and right subclavian arteries are located in the thorax (chest) underneath the clavicles (commonly known as the collarbones). The left subclavian artery receives oxygenated blood from the aortic arch (the top portion of the largest artery in the body that carries blood away from the heart).

Are there 2 brachiocephalic veins?

There is no brachiocephalic artery for the left side of the body. The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic veins.

What are the 3 arteries coming off the aortic arch?

The three main branches of the aortic arch are the brachiocephalic (innominate) artery (dividing into the right subclavian and common carotid arteries), the left common carotid artery, and the left subclavian artery.

How many types of aorta are there?

The aorta can be divided into four sections: the ascending aorta, the aortic arch, the thoracic (descending) aorta and the abdominal aorta.

Why is it called brachiocephalic?

formation of superior vena cava The brachiocephalic veins, as their name implies—being formed from the Greek words for “arm” and “head”—carry blood that has been collected from the head and neck and the arms; they also drain blood from much of the upper half of the body, including the upper part…

What happens if the left subclavian artery is blocked?

Subclavian Steal Syndrome is a blockage of the subclavian artery which sits under the collarbone. It delivers blood to the arm and brain. The blockage causes the blood to flow in reverse. The arm “steals” blood flow from the blood which was intended for the posterior (back side) of the brain.

What happens when subclavian artery is blocked?

The symptoms that do occur are tied to the area that is blocked. You may experience arm pain or muscle fatigue when using your arms above your head, or doing any activity that demands more oxygen-rich blood flow to the arms. Other symptoms can include: Dizziness (vertigo) with arm activity.

What are the two largest veins in the body?

Together, your superior vena cava and inferior vena cava collect deoxygenated blood from your whole body and bring it back to your heart for new oxygen. This is why the vena cava veins are the largest veins in your body.

What is the most common abnormality of the aorta?

ARSA is the most common anomaly associated with left aortic arch and is predominant in females (31). This anomaly results from involution of right arch between the right subclavian and the right common carotid artery along with regression of the right ductus arteriosus.
