Branches of Aorta- Anatomy, tests, diseases & Treatment of Aorta

The Aorta is the largest artery of the human body, also referred it as a pumping chamber, because it is the main source through which the heart pumps the oxygenated blood via the whole body. It is specifically beginning at the top of the left ventricle and extending down to the end of the abdomen, but now it is going to split further into two arteries. However, the heart pumps blood from the left ventricle into the aorta by the use of the aortic valve.

branches of aorta

Aorta and its branches:

As an aorta a prolong tube approximately a height of the foot and has a one-inch diameter. Aorta is sub divided into four sections:

Ascending aorta :

Ascending aorta the very first essential part of the aorta, that begins from the left ventricle of the heart and after join the aortic arch. The right and left coronary arteries that are responsible for carry oxygenated blood to the heart muscle start from the ascending aorta.

Main branches:

  1. Left coronary artery.
  2. Right coronary artery.

Aortic arch:

The aorta is the following leading biological part of the aorta; it begins above the heart between the ascending together with descending aorta. All the oxygenated blood carried from the heart to the combination of cells (tissue) of the body enters the aorta, so that is why it is most beneficial artery in the body.

Main branches:

From right to left.

  1. The brachiocephalic trunk.
  2. The left common carotid artery.
  3. The left subclavian artery.

Thoracic aorta:

The thoracic aorta is a part of the aorta, the leading artery inside the body, within the chest. Particularly, the thoracic aorta is the part of the aorta that begins after the arch of the aorta and joins directly down to the diaphragm, the terrific muscle that divides the chest from the tummy.

Main branches:

  1. Bronchial arteries.
  2. Oesophageal arteries.
  3. Posterior intercostal arteries.
  4. Superior phrenic arteries.

Abdominal aorta:

The abdominal aorta is the most significant artery in the stomach that delivers oxygenated blood to the bodily organs as well tissues of the stomach, pelvis, and then legs. It descends from the thorax since a continuation of the thoracic aorta and limbs many times to form the leading arteries of the stomach.

Main branches:

  1. Inferior phrenic arteries (paired).
  2. The coeliac trunk.
  3. The superior mesenteric artery.
  4. The middle suprarenal arteries (paired) Renal arteries (paired).
  5. Gonadal (testicular or ovarian) arteries (paired).
  6. Lumbar arteries Inferior mesenteric artery.
  7. The median sacral artery.
  8. The left and right common iliac arteries (terminal branches).

Learn the branches of abdominal aorta in detail.

Aorta Conditions:

Aortic Atherosclerosis:

Atherosclerosis (arteriosclerotic vascular disease) is a disorder in which the arteries turn out to be contracted and hardened because of an extreme build-up of fat around the artery wall structure. The malady hinders the flow of oxygenated blood around the entire body, posing severe cardiovascular problems.

Aortic Aneurysm:

An abdominal aortic aneurysm is a dilation section of the aorta which is within the stomach. It typically leads to zero conditions until it bursts. An abdominal aortic can often be deadly. If it, lower than 5 .5 cm has a minimal possibility of burst. The process to overcome an aortic aneurysm could be encouraged when it is in excess of 5 .5 cm, as above this size the threat of burst raises greatly. Men 65 yr old and over should be run their routine scan to screen for AAA.

Aortic Dissection:

Aortic dissection is a dangerous situation wherein there is certainly a rip in the wall surface of the leading artery taking oxygenated blood away from the heart. Since the rip of the wall lengthens along the wall surface of the aorta, bloodstream can circulate between the layers of the blood vessel wall. This could cause aortic rupture or decreased blood flow to bodily organs.

Aortic Stenosis:

Constriction of the aortic valve, causing the heart to stress to pump one oxygenated blood through the whole body. Rheumatic fever is regarded as the typical reason for aortic stenosis, that may trigger chest pain or breathing difficulties.

Bicuspid aortic valve:

A bicuspid aortic valve is a cardiac issue which is normal as a consequence of an innate distortion. An ordinary aortic valve has 3 cusps, while a bicuspid valve has merely 2. Concerning 1-2% of the masses have bicuspid aortic valves, however, the infection is almost two times general in young adult males. The bulk may cause simply no troubles. However, particularly as they get older, a bicuspid aortic valve can become calcified, which can result in varying courses of the severity of aortic stenosis or aortic regurgitation, that can appear as murmurs. If these turn out to be extreme enough, they might need cardiac surgical treatment.

Aortic regurgitation:

Aortic insufficiency a well-known name of this disease. That is mainly caused due to blood moving in a backward manner via the intense narrow closed aortic valve and enters into the left ventricle.

Aorta Tests:


It is the test in which we inject some kind of protein or dye called “catheter” into the aorta, helps in envision the flow of blood stream.

Magnetic resonance imaging:

An MRI scanner that produces special kind of radio waves, that further bends towards the magnetic field, in order to make envision images of the aorta.

Transthoracic echocardiogram:

A dye is being put in the middle of the chest and starts producing an ultrasound wave (UV), to the aorta and heart. After, a while an ultrasound creates an imaginary view of aorta while transthoracic echocardiograms.

Transoesophageal echocardiogram:

It is a test that is used to produce an imaginary and envision the image of the aorta (heart), by sending the sound beam that directs to your heart.

Abdominal ultrasound:

It is really a costly test, in which we direct the way of sound waves (UV), towards the abdominal cavity, spleen, pancreas, and kidneys, in to check the threat of rupture.

Aorta Treatments:

Aortic aneurysm repair:

There are two following procedures for this method:

However, when aortic aneurysms reach 5.5 cm wide or more, heart surgery is must require. This method implies by an incision in the abdominal cavity.

Aorta grafting means when a part of the aorta (that is harshly affected) at that time may be surgically replaced by a synthetic mesh.

Aortic valve replacement:

In this critical method, surgeon replaces the damaged aortic valve by the new aortic valve that takes from either man or a pig.
