Acute cerebral infarction is a common acute cerebrovascular disease, with high incidence rate, mortality and disability rate, which brings heavy burden to patients and families. In recent years, with the continuous development of medical technology, thrombectomy and thrombolysis have become important treatment methods for acute cerebral infarction. This article will provide a detailed introduction to the thrombolytic therapy for acute cerebral infarction, helping you understand this important life-saving measure.
1、 Overview of Acute Cerebral Infarction
Acute cerebral infarction refers to a series of pathological and physiological processes caused by cerebral vascular obstruction, resulting in brain hypoxia, metabolic abnormalities, and subsequently leading to brain cell damage and death. According to the location and extent of obstruction, acute cerebral infarction can be divided into thrombotic cerebral infarction, embolic cerebral infarction, and other types. The main causes include arteriosclerosis, hypertension, diabetes, hyperlipidemia, etc.
The typical symptoms of acute cerebral infarction include sudden speech disorders, hemiplegia, hemiparesis, binocular syndromic hemianopia, dizziness, vomiting, etc. Once patients with acute cerebral infarction experience the above symptoms, they should seek medical attention as soon as possible to avoid missing the best treatment opportunity.
2、 The treatment principle of thrombectomy and thrombolysis
Thrombolysis is an emergency treatment measure for acute cerebral infarction, and its main principle is as follows:
1. Thrombolysis: Through instruments such as catheters and stents, the thrombus blocking the cerebral blood vessels is removed to restore cerebral blood flow. At present, thrombectomy treatment mainly includes mechanical thrombectomy and intravascular laser therapy.
2. Thrombolysis: Dissolving blood clots through medication to unblock blocked cerebral blood vessels and restore cerebral blood flow. There are two main types of thrombolytic drugs: fibrinolytic agents and urokinase. Fibrinolytic agents can directly dissolve thrombi, while urokinase can promote fibrinolysis inside the thrombus.
3、 The timing and method of thrombectomy and thrombolysis for acute cerebral infarction have strict time requirements, and it is generally believed that the best treatment effect is achieved within 6 hours after the onset of the disease. However, in practical operation, the timing of treatment may be delayed due to factors such as patient visit time and medical resources. Therefore, early detection of symptoms of acute cerebral infarction and seeking medical attention as soon as possible is the key to improving the success rate of treatment.
The main methods of thrombolytic therapy include: 1. Intravenous thrombolysis: thrombolytic drugs are injected into the patient's body through the intravenous route to dissolve the thrombus. This method is suitable for patients with acute cerebral infarction, but may pose a risk of bleeding.
2. Arterial thrombolysis: Directly inject thrombolytic drugs into blocked cerebral blood vessels to improve the thrombolytic effect. This method is suitable for thrombotic cerebral infarction, but the operation difficulty is relatively high.
3. Mechanical thrombectomy: Use instruments such as catheters and stents to remove thrombi that block cerebral blood vessels. This method is suitable for acute large-area cerebral infarction, but there may be a risk of re blockage.
4、 The therapeutic effect and risks of thrombectomy and thrombolysis
The effectiveness of thrombectomy and thrombolysis treatment mainly depends on the following factors: the type of blocked blood vessel, the time from onset to treatment, the age and physical condition of the patient, etc. Overall, thrombolytic therapy has a significant effect on the treatment of acute cerebral infarction, saving patients' lives and reducing disability rates.
However, there are also certain risks associated with thrombolytic therapy, mainly including:
1. Bleeding risk: Thrombolytic drugs may cause bleeding in the patient's body, such as gastrointestinal bleeding, intracranial bleeding, etc.
2. Re infarction: After thrombectomy treatment, patients may be at risk of re infarction.
3. Vascular injury: During mechanical thrombectomy, complications such as vascular injury and stenosis may occur.
Thrombolytic therapy for acute cerebral infarction is an emergency treatment measure that is of great significance in saving patients' lives and reducing disability rates. Patients and their families should fully understand the severity of acute cerebral infarction. Once symptoms appear, seek medical attention immediately to save valuable time for treatment. At the same time, doctors should develop a reasonable treatment plan based on the specific situation of the patient to ensure the safety and effectiveness of thrombolytic therapy. With the support of modern medical technology, we have reason to believe that more patients with acute cerebral infarction will benefit from thrombolytic therapy and regain their lives.
