Plaque formation at the bifurcation of the innominate artery refers to the development of atherosclerosis at the bifurcation of the innominate artery due to a combination of factors such as hyperlipidemia and hypertension. The innominate artery is a very important artery emanating from the aorta and is used to supply blood to the right upper limb, right cerebellum and right brain. Due to the turbulent blood flow at the bifurcation of the innominate artery, damage to the lining of the blood vessel is likely to be caused by the rapid impact of the blood flow. If the patient has a primary disease such as hypertension, hyperlipidemia, diabetes mellitus, etc., under the action of these factors, the vascular damage is prone to lipid deposition and platelet aggregation, causing atherosclerosis and the formation of plaques at the bifurcation. Due to the rapid blood flow at the bifurcation of the innominate artery, the plaque formed can easily dislodge and embolize the arteries of the right upper limb, carotid artery or vertebral artery, resulting in serious consequences. Therefore, it is recommended to cooperate with your doctor to receive active treatment for plaque formation at the bifurcation of the unnamed artery.
