Cerebrovascular disease, also known as “stroke”, is a general term for a group of diseases including cerebral thrombosis, cerebral hemorrhage, subarachnoid hemorrhage, and cerebral blood supply deficiency. Currently, cerebrovascular disease has become one of the top three causes of death in China, and is the first cause of disability. The sequelae caused by this disease, such as hemiplegia, impose a huge burden on the patients, their families and society. What are the causes of cerebrovascular disease? First of all, in middle-aged and elderly people, the primary cause is caused by cerebral arteriosclerosis, intravascular plaque formation and small vessel occlusion, especially in patients with hypertension, diabetes, hyperlipidemia, etc. In young patients, most of them are caused by congenital abnormal development of blood vessels, such as smog, cerebrovascular malformation, etc. Other rare causes are seen in infections, trauma, etc. Cerebrovascular disease manifests in various ways, the most common symptoms are: poor speech, numbness and weakness of the arms and legs of the deviated body, etc. In severe cases, there can be headache, vomiting, and even convulsions and coma, etc. Less severe manifestations include dizziness, dizziness and weakness, transient slurred speech, weakness of the arms and legs, etc. Individuals also have difficulty seeing with their eyes, black haze in front of their eyes, etc. The treatment of cerebrovascular disease has made great progress in the last 10 years, firstly, imaging, brain CT and MRI are becoming more and more common, but the most crucial thing is that more and more doctors are paying attention to the examination of the cerebral vessels themselves, so that many patients with pre-stroke attacks, such as cerebral stenosis and cerebral aneurysm, are found, unlike many doctors who used to focus only on whether there is an infarction and the size of the infarction. In fact, some patients with mild cerebral infarction or even just insufficient cerebral blood supply (headache, dizziness, etc.) have serious cerebrovascular problems, and if they are not treated in time, they often have severe hemiplegic attacks and lose the best time for treatment, and I always feel sorry for them when I see such patients in clinical medicine. The main methods of treatment are as follows: Drug therapy: for patients with small vascular lesions or large vessel occlusion Interventional therapy: for patients with large vessel stenosis, such as carotid artery, vertebral artery, basilar artery, middle cerebral artery stenosis, etc.; aneurysm rupture can be solved by minimally invasive interventional therapy for most patients. Comprehensive treatment: pay attention to the regulation of emotion, healthy diet, control of hypertension, diabetes, quit smoking and alcohol, etc. Look at the following typical case: cerebral infarction is very small, if you feel well and then neglect the etiological treatment, it is likely to lead to severe hemiplegia, and then you will regret it. Fortunately, the patient in this case was examined and found to have severe stenosis of the basilar artery, and was given stenting treatment, which completely opened the stenosed vessel and completely restored health, eliminating the risk of another hemiparesis.
