Transient ischemic attack (TIA): commonly known as mini-stroke, is a transient or transient brain dysfunction caused by cerebrovascular lesions, commonly caused by atherosclerotic plaques disintegrating and dislodging to form tiny thrombi, resulting in ischemic blockage of distal cerebral vessels, etc. It can manifest as transient transient blackness, weakness or numbness of one side of the face or limbs, blurred speech, cognitive and behavioral abnormalities, or dizziness, dizziness, nausea, vomiting. nausea, vomiting, or transient unconsciousness, sudden limb weakness falling to, partial blindness or loss of vision in both eyes. Clinical symptoms tend to disappear completely within one hour, but are prone to recurrent attacks. Recent frequent or recurrent TIAs are prone to stroke within a short period of time and are a precursor to stroke, requiring emergency medical treatment. It is often neglected by patients and their family members because of the short recovery time after the attack, and no early intervention is made, and they are often sent to the hospital only when cerebral infarction occurs, paralysis and impaired consciousness appear, delaying the best prevention and treatment period. Therefore, once TIA occurs, you should go to the hospital as soon as possible, and if possible, you can have a DSA cerebral angiography examination as soon as possible to get a clear and comprehensive understanding of cerebrovascular disease, and timely cerebrovascular intervention to effectively remove high-risk lesions such as severe plaque stenosis and vascular malformation, which can significantly reduce the occurrence of stroke events. In general, you can take aspirin, Tongxinluo, earth kinase, nimodipine and other drugs to prevent and control blood pressure, blood glucose and blood lipids, etc. Pay attention to rest, drink water properly, avoid exertion, staying up late, excitement and cold. Stroke: divided into two categories: hemorrhagic stroke (cerebral hemorrhage, subarachnoid hemorrhage) and ischemic stroke (cerebral infarction), is a common and frequent disease that endangers human health, and the age of onset is getting younger and younger. There are 2-2.5 million new strokes in China every year, of which about 200,000-250,000 are in middle-aged and young people. Cerebrovascular disease has become the “number one killer” of Chinese residents, and is also the most disabling disease among all single diseases, with about 3/4 of surviving patients disabled. Since stroke can cause secondary damage and further aggravation of the disease, timely hospitalization is expected to control or reduce the damage of the disease. Interventional thrombolytic therapy is currently one of the most effective methods for the treatment of acute cerebral infarction at home and abroad, with relatively high safety, rapid results, good prognosis and mild complications compared with traditional treatment methods. If patients with acute cerebral infarction can receive DSA cerebrovascular artery interventional thrombolytic therapy within 6 hours after the onset of the disease, the blocked blood vessels may be dissolved and recanalized, thus improving the condition rapidly. Moreover, the earlier the treatment is started, the better the prognosis is, and the fewer and lesser the complications and sequelae. In addition, it is also important to actively control the high-risk factors of cerebrovascular disease. Common risk factors include hypertension, diabetes, hyperlipidemia, coronary artery disease, carotid atherosclerosis plaque, obesity, smoking, etc. The risk of stroke increases by about 30% for each combined risk factor, and if two to three risk factors are not effectively controlled, it is only a matter of time before a stroke occurs. Therefore, active and effective control of high-risk factors is the most fundamental and effective means to prevent and treat stroke. The possible manifestations of acute stroke include: 1. sudden or gradual weakness or paralysis of one limb, or incontinence or convulsions; 2. slanting of the mouth, salivation, slurred speech, aphasia or difficulty in understanding speech; 3. numbness or foreign body sensation on one side of the face or limb; 4. sudden transient or persistent confusion or coma; 5. sudden vertigo, unstable standing and walking, or nausea, vomiting, tinnitus; 6. Sudden severe headache, or vomiting, twitching of limbs, etc.; 8. Sudden personality abnormalities or abnormal mental or behavioral problems, memory loss, etc. Atherosclerotic plaque: It is caused by various reasons (e.g. hypertension, diabetes, hyperlipidemia), which leads to the breakage and roughness of the inner membrane of arterial blood vessels and the formation of an unstable wall plaque, which gradually grows and increases, causing the blood vessels to become brittle and hard, narrowed and occluded, which can lead to a serious lack of blood supply to the brain vessels, frequent dizziness, headache, and even memory loss, intelligence loss, dementia and so on. What is more dangerous is that the plaque may fall off at any time under the impact of blood flow, causing distal cerebrovascular embolism, which is the most fundamental cause of transient ischemic attack (TIA) and cerebral infarction. In addition, many patients with moderate to severe arterial stenosis due to atherosclerotic plaque formation usually do not necessarily show obvious symptoms, so that many patients do not pay enough attention to timely intervention and treatment to release the risk of stenotic plaque, and eventually regret due to the occurrence of critical stroke events. The main examination methods are: transcranial Doppler (TCD), carotid color ultrasound, DSA whole brain angiography, etc. Cerebral angiography is currently the most clear and comprehensive advanced minimally invasive detection method for examining cerebrovascular lesions and understanding blood vessels, with high safety and few adverse reactions, and is currently the recognized gold standard for diagnosing cerebrovascular diseases at home and abroad. Treatment: 1) General treatment: Strictly control high blood pressure, high blood sugar, high blood lipid, these high-risk diseases, do not smoke, alcohol, do not eat too salty and too greasy food, appropriate physical exercise. (2) Drug therapy: statin lipid-lowering drugs, aspirin, Tongxinluo, etc. (3) Cerebrovascular interventions: Cerebrovascular interventions such as angioplasty and stent implantation can completely remove moderate to severe vascular plaque and stenosis lesions and remove high-risk factors for stroke, thus effectively preventing the occurrence of serious stroke events. Post-stroke sequelae: Patients can be given some drugs to improve cerebral blood supply and microcirculation, such as nimodipine, Tongxinluo, aspirin, atorvastatin, etc., and pay attention to the control of hypertension, hyperlipidemia, diabetes, smoking, obesity and other stroke risk factors, a light diet, appropriate daily physical activities and functional rehabilitation exercises of the limbs, and regular outpatient review.
