Carotid insufficiency is a pathological condition that occurs when blood flow through the carotid artery is reduced or completely stopped. This vessel provides blood flow to the brain and other important organs. Insufficiency of the carotid artery can occur at various levels: both at the site of its confluence with the subclavian artery, and at the level of the aortic arch or abdominal aorta. In the first case, the so-called upper type of insufficiency most often occurs, in which the blood supply to the brain is limited. If the deficiency exists below the navel, then its lower type develops. This condition is very common in people, especially the elderly. Their life path may be disrupted due to the fact that significant changes occur in the brain, which ultimately lead to diseases of the heart and vascular system. In fact, anyone can encounter a similar problem, so let’s look at each type of carotid insufficiency in more detail.
Conventionally, the upper type of carotid artery is divided into two types: late and early. Patients who have had the first type are more likely to suffer from symptoms of chronic carotid artery insufficiency, such as headache, nausea, and dizziness. Concerning
