Innominate artery

Innominate artery (also known as brachiocephalic artery or brachiocephalic trunk) is a major blood vessel in the upper body that supplies blood to the right side of the head, neck, and arm. It is the first and largest artery branching from the aortic arch and is a central component of the circulatory system.

Anatomy

The innominate artery originates from the aortic arch and ascends towards the neck. It divides into the right common carotid artery and the right subclavian artery. The right common carotid artery further divides to supply blood to the right side of the head and neck, while the right subclavian artery supplies blood to the right arm.

Function

The primary function of the innominate artery is to transport oxygenated blood from the heart to the right side of the head, neck, and arm. This is crucial for the functioning of the brain and muscles in these areas.

Clinical significance

Diseases of the innominate artery can lead to serious health problems. These include atherosclerosis, aneurysm, and arteritis. These conditions can cause symptoms such as dizziness, fainting, and even stroke. Treatment options include medication, lifestyle changes, and in severe cases, surgery.
