What Is Cerebral Ischemia?

(1) Atherosclerosis. Some cerebral arterioles are temporarily occluded. When the collateral circulation is established and reopened in time, the blood supply improves and the symptoms disappear within 24 hours.

Cerebral ischemia

The transient insufficient blood supply to the brain with symptoms is called a transient ischemic attack and is a common acute cerebrovascular disease. Sudden onset of the patient, similar to the manifestations of cerebral hemorrhage or cerebral infarction, usually fully recovered to normal within 24 hours, often frightening family members, but can be recurrent. Patients with transient ischemic attack may develop cerebral infarction within 1 to 5 years. One third to two thirds of patients with cerebral infarction have had a transient ischemic attack

Risk factors of transient cerebral ischemia caused by cerebral ischemia

(2) Hypertension, which causes cerebral vasospasm, poor blood flow and insufficient blood supply.

(3) Microthromboembolism is eliminated by the body itself, and blood circulation reopens, but it can cause the same symptoms to reappear when recurring.

(4) Thrombocytosis causes high blood viscosity, insufficient blood oxygen content, and anemia, heart disease, and myocarditis can cause transient ischemic attacks.

(5) Hyperlipidemia.

(6) Diabetes and complications.

(7) Excessive use of the brain.

(8) emotional.

(9) Cold (generally over 40 years old)

(10) Exhausted (the elderly)

Clinical manifestations of cerebral ischemic transient ischemic attack

1. Sudden, transient, focal neurological deficits recovered within 24 hours without sequelae;

The symptoms of focal neurological deficits are:

(1) Hemiplegia, numbness, loss of sensation, visual impairment, and ball paralysis;

(2) Dizziness, headache, tinnitus, dark eyes, numbness of the face, weakness of the limbs, coughing with drinking water, and slurred speech.

Many of the above symptoms can last for several minutes or hours to return to normal. A few patients last for more than ten hours, but all return to normal within 24 hours.

2. Repeated clinical symptoms appear repeatedly.

3, the age of onset is more than 50 years old, with a history of heart disease and atherosclerosis.

Cerebral ischemia symptoms

What are the symptoms of cerebral ischemia? Transient ischemic attack is caused by the arterial blood vessels supplying blood in the brain. Temporary dysfunction in the brain tissue. The disease often manifests as sudden onset of dizziness, vertigo, dizziness, tinnitus, unstable walking, severe confusion, blindness or diplopia, unilateral or bilateral limb weakness and paresthesia, inexplicable falls, and inability to speak Fluent and so on.

Cerebral ischemia treatment

1. Treatment for primary diseases such as hypertension, heart disease and atherosclerosis.

2. Anticoagulation therapy.

3. Application of vasodilators.

4. Reduce blood fat and blood viscosity.

5. Vascular surgery, resection of vascular intima and sclerotic plaque or vasodilator stent forming.

6, symptomatic treatment.

Cerebral ischemia

Patients with cerebral ischemia should actively participate in physical exercise, such as walking, jogging, Tai Chi, Qigong and so on. However, do not engage in excessively intense activities. At the same time, avoid overwork, keep your life regular, eliminate alcoholism, strictly quit smoking, arrange your diet reasonably, eat less animal fat and high cholesterol food, and eat more soy products, fish, fresh vegetables and fruits. . Should also go to the hospital regularly to check blood pressure, blood lipids, blood sugar, cholesterol, fundus, electrocardiogram and cardiac function, and when abnormalities are found, actively treat them.

Cerebral ischemia rescue measures

Frequent attacks, the possibility of cerebral infarction in the near future is very large, and should be actively treated to prevent the occurrence of cerebral infarction.

(1) Actively treat risk factors such as hypertension, hyperlipidemia, heart disease, diabetes, and cerebral arteriosclerosis.

(2) Anti-platelet accumulation drugs, such as pansentin, aspirin enteric-coated tablets, etc.

(3) Improve cerebral circulation, use sibilin, cerebrozine

(4) Others such as papaverine hydrochloride, vitaminol and Chinese medicine can be used.

(5) If there is a small cerebral infarction lesion in the brain CT examination, treat it according to the cerebral infarction.

(6) It is recommended to go to the hospital for further examination during or after a brief attack, and then treat the cause.

Cerebral ischemic stroke

(Acute cerebrovascular disease)

What is cerebral ischemia ?

Transient ischemic attack, referred to as TIA, is also called transient ischemic attack or minor stroke. It refers to brain dysfunction caused by a decrease in cerebral blood flow in a short time. The duration of each illness lasts shortly, usually seconds, minutes, or hours, etc., up to 24 hours. The symptoms often come quickly and disappear quickly, and they are easily ignored by people without any sequelae after recovery. In fact, although the symptoms of TIA are mild, the consequences are serious. If not treated in time, according to statistics, about 25% to 40% of patients will have severe cerebral infarction within 5 years and threaten patients' lives. Therefore, medical scientists often see it as a precursor or a danger signal of cerebrovascular disease.

There are many causes of TIA, such as hypertension, hyperlipidemia, atherosclerosis, and diabetes are the main and most common causes. Excessive use of the brain, emotional excitement, cold, fatigue can promote it.

There are many symptoms of TIA, ranging from mild to severe. Those who are mild are several times a year, those who are severe are several times a day, and dozens of times a month. Its symptoms can be roughly divided into two groups. One is hemiplegia, hemiplegia, sudden darkness or blindness, and aphasia caused by ischemia of the carotid artery system; one is vertigo, nausea, vomiting, tinnitus, deafness and face caused by ischemia of the vertebral basilar artery system Feeling impaired. The above two groups of symptoms can occur independently in the same patient, or they can occur sequentially or simultaneously.

After the occurrence of TIA, it must not be ignored and should be actively controlled. First of all, under the guidance of a doctor, the traditional Chinese medicine and other vasodilators for activating blood circulation and stasis should be appropriately selected, and they should also actively participate in physical exercise, such as walking, jogging, playing Taijiquan, and practicing qigong. However, do not engage in excessively intense activities. At the same time, avoid overwork, keep your life regular, eliminate alcoholism, strictly quit smoking, arrange your diet reasonably, eat less animal fat and high cholesterol food, and eat more soy products, fish, fresh vegetables and fruits. . Should also go to the hospital regularly to check blood pressure, blood lipids, blood sugar, cholesterol, fundus, electrocardiogram and cardiac function, and when abnormalities are found, actively treat them.

How is cerebral ischemia diagnosed?

(1) It usually occurs in people over 50 years old, and often has a history of hypertension, atherosclerosis or diabetes, heart disease, and cervical disease.

(2) Sudden onset, often sudden onset, symptoms peak within seconds or minutes.

(3) It is mostly episodic, with a short course and often transient. The duration of each episode is usually a few minutes or hours, and the longest is no more than 24 hours.

(4) Repeated attacks, most of which occur several times a day, at least once every few months or years, but the symptoms and signs of each attack are basically the same.

(5) No increase in intracranial pressure, and more unconscious disturbance.

(6) Clinical manifestations. Hemiplegia, aphasia, blindness, sensory disturbance of the body, or those with psychiatric symptoms are ischemic attacks of the internal carotid artery system; if dizziness, facial paralysis, difficulty swallowing, ataxia, and cross paralysis are present Is the ischemic attack of the vertebral basilar artery system.

(7) Brain CT examination: normal or visible lacunar infarction.

How ischemia treats transient ischemic attacks

According to reports, about 1/2 to 3/4 of patients with transient ischemic attacks develop cerebral infarction within 3 years. After treatment, transient ischemic attacks can be terminated, or 79.6% of the patients can be reduced without treatment. Automatically stop authors accounted for only 20.38%. Therefore, transient ischemic attacks should be actively treated to reduce blood viscosity, adjust blood hypercoagulability, control and maintain blood pressure within the normal range, terminate and reduce transient ischemic attacks, prevent or delay brain Occurrence of infarction.

(1) Anti-platelet aggregation treatment is mainly to inhibit platelet aggregation and release so that it cannot form microthrombus. These drugs are safe, simple, and easily accepted by patients. Enteric-coated aspirin is commonly used, 50 to 100 mg, once a day; persantin is 50 to 100 mg, 3 times a day.

(2) Expansion treatment of low-molecular-weight dextran and 706-generation plasma have the effects of dissolution, improvement of microcirculation, and reduction of blood viscosity. Low-molecular-weight dextran or 706-generation plasma 500 ml intravenous drip is usually used once a day for 14 days as a course of treatment. .

(3) Anticoagulation therapy If the patient has frequent seizures, the efficacy of other drugs is not good, and there is no contraindication to bleeding disorders, anticoagulation therapy can be used. Commonly used drugs heparin, dicoumarin and so on. Such as heparin can be used in ultra-small doses of 1500 ~ 2000 plus 5% ~ 10% glucose 500 ml intravenously, once a day, 7 to 10 days for a course of treatment. Can be repeated if necessary, the interval between treatments is 1 week, but during the application, pay attention to bleeding complications.

Sodium alginate is a new type of heparin-like drug, which can reduce fibrinogen and factor related antigens, prolong prothrombin time, and has anticoagulant, thrombolytic, lipid-lowering and viscosity-reducing effects. Can be taken orally orally, 50 to 100 mg orally 3 times a day; 2 to 4 mg intravenously plus 500 ml of 10% glucose, 20 to 30 drops per minute, 10 days is a course of treatment, and 2 to 3 courses can be combined .

(4) Vasodilator therapy can be selected from betadine, cerebrazine, cibilin, xidezhen, kalan tablets and so on. Commonly used doses: Betadine 10 mg, 3 times a day; Cerebrolyzine 25 mg, 3 times a day; Sibilin 6 mg, twice daily; Xidezhen 3 mg, 3 times daily; Caran Tablets 5 mg, 3 times a day, orally.

(5) The traditional Chinese medicine Danshen, Chuanxiong, Taoren, safflower, etc., has the functions of promoting blood circulation, improving blood circulation, reducing blood viscosity, and has a certain effect on the treatment of transient ischemic attacks.

In patients with intracranial arterial stenosis confirmed by cerebral angiography or Doppler, surgical treatment can be considered when drug treatment is not effective.
