Carotid artery stenosis is not to be taken lightly, it is closely related to our brain health. Especially for some middle-aged and elderly patients who suffer from trigeminal diseases, they should pay more attention to the health of carotid arteries. A healthy artery can supply blood to the human brain at all times, and for carotid stenosis caused by hardened plaque or other reasons, many people are not easily detected because the initial performance symptoms are not very obvious, thus missing the time for early intervention, so it is of great significance to understand the early distress signals issued by this disease for the treatment of carotid stenosis. The recurrence of cerebral infarction may also be a major signal from carotid stenosis. One is atherosclerotic plaque, because once it is formed, the blood vessels will be blocked and blood cannot proceed to brain tissue in time, thus leading to blood supply disorder and triggering brain infarction. Another aspect is that after the plaque is dislodged, it will enter the brain with the blood flow, and then block the distal arteries, causing acute cerebral infarction, which often happens more suddenly than the first one. Secondly, when carotid artery stenosis occurs, the lumen of the blood vessel becomes narrower and the blood flow rate is drastically reduced, resulting in severe cerebral blood supply deficiency. Many people tend to experience dizziness, weakness, numbness of the limbs, and in some cases, slurred speech and difficulty speaking, which is often referred to as aphasia. In addition, after having carotid stenosis, most people will also suffer from cognitive impairment, transient vision loss, and visual field defects, which will have a serious impact on patients’ normal life, work, and study. In summary, carotid stenosis is a very dangerous cerebrovascular disease that must be taken seriously and treated as early as possible to avoid life-threatening health problems. Can right carotid artery occlusion be treated conservatively? Currently, bypass surgery is carried out to treat carotid occlusion, so patients can go to regular hospitals to receive surgery for either right or left carotid occlusion.
