The carotid artery, located on both sides of the neck, is an important blood vessel that connects the heart to the head and face, and plays a pivotal role in supplying blood to the brain in particular. When the carotid artery is narrowed for a number of reasons, it can cause a lot of discomfort to the body. First of all, carotid artery stenosis may cause a lack of blood supply to the brain, leading to a series of ischemic symptoms and neurological dysfunction. There may be tinnitus, blurred vision, dizziness, headache, memory loss, drowsiness or insomnia, and excessive dreaming. Transient ischemic attacks such as vertigo and black membrane may also occur. In severe cases, there may be episodes of fainting gu or even hemiparesis, aphasia, coma, and in a few patients, vision loss, hemianopia, diplopia, or even sudden blindness. For the treatment of carotid stenosis, there are internal conservative treatment and surgical treatment. Internal conservative treatment is mainly to improve the symptoms and control the development of the disease through some drugs. So, what Chinese medicine is good for carotid stenosis? In fact, not all patients with carotid artery stenosis can take conservative treatment measures. In clinical medicine, for stenosis degree less than 50%, internal conservative treatment can be taken. When the degree of stenosis is greater than 50%, surgical treatment is required. Carotid endarterectomy, a powerful weapon in the treatment of carotid stenosis, has outstanding results. This procedure is performed under a microscope, which ensures the safety of the operation. During the operation, the carotid artery wall is incised, the intimal plaque where the lesion occurs is precisely found and removed, so that the inner wall of the carotid artery is restored to smoothness, the carotid lumen is restored to its original size, blood flow is restored to smoothness, and cerebral ischemia is improved.
