Cerebral embolism


What is a brain embolism?
Cerebral embolism refers to various abnormal emboli that enter the intracranial arteries with blood circulation, causing acute occlusion of the cerebral arteries and leading to ischemic hypoxic necrosis of the brain tissue in the supplied area. The onset is usually very sudden and dangerous, with patients rapidly developing limb paralysis, speech dysfunction, facial paralysis, and in some cases, coma, seizures, and other clinical manifestations. The most common source of embolism is the heart, such as atrial fibrillation or myocardial infarction forming mural thrombi that dislodge and enter the brain causing an embolism. Additionally, there are non-cardiac sources of embolism, such as the detachment of atherosclerotic plaques causing an embolism, as well as air embolisms and cancer cell embolisms. Cerebral embolism is an emergency and severe condition that requires prompt medical attention.


What department should one go to for a cerebral embolism?
Patients with cerebral embolism should visit the department of neurology. Cerebral embolism is not a special disease but rather one type of cerebral infarction. Cerebral infarction generally includes two types: cerebral thrombosis and cerebral embolism. The former refers to the formation of a thrombus at the site of the vessel occlusion. The latter involves a thrombus originating from another location, which blocks the vessel at the infarct site. The sources of such thrombi are varied, with the most common being from the heart, frequently seen in patients with long-term chronic atrial fibrillation. This condition forms a mural thrombus in the atrium, which, during episodes of atrial fibrillation, can detach, be flushed by the blood stream into the brain, and cause cerebral embolism. Secondly, it occurs in cardiac valve diseases, such as rheumatic heart disease, mitral valve alterations, and others. There are also some other sources of thrombi, such as tumor-induced cancer, amniotic fluid embolism in pregnant women, and fat embolism in patients with fractures.


Which department should I go to for a cerebral embolism?
The patient has experienced a cerebral embolism, and it is definitely recommended to seek appropriate medical care in neurology. Neurologists have seen many patients with cerebral embolism and have rich experience in the pathogenesis, diagnosis, and treatment of this disease. The onset of cerebral embolism is quite severe, and patients generally may have a history of cardiac diseases, such as atrial fibrillation. It is crucial to go to the hospital as soon as possible if a cerebral embolism occurs. If within the time window for thrombectomy, such as within eight hours, relevant thrombectomy treatment can be performed. Additionally, some hospitals carry out thrombectomy treatments in neurosurgery or interventional departments. Therefore, if a cerebral embolism requires surgical treatment, one can also visit the interventional department or neurosurgery. After the condition of a cerebral embolism patient stabilizes, routine anticoagulation therapy is necessary to prevent a recurrence of the cerebral embolism.


Can you exercise with a cerebral embolism?
Brain embolism is a form of cerebral infarction. The mechanism of its occurrence mainly involves abnormal objects entering the arteries, causing occlusion in the cerebral arteries and leading to brain embolism. Patients may experience paralysis, limb numbness, speech impairments, and in severe cases, even coma. The most common cause of brain embolism is due to atrial fibrillation or myocardial infarction causing mural thrombi. These dislodged thrombi travel to cerebral arteries, causing brain embolism. Generally, during the acute phase of brain embolism, bed rest is recommended along with some bedside functional exercises, such as active and passive movements of the limbs. Additionally, cardiac function must be considered since cardiac function is generally compromised in patients with brain embolism. If the treatment of brain embolism progresses well into the recovery or residual phase, and if cardiac function permits, moderate exercise such as brisk walking and slow jogging may be appropriate, but it is essential to protect the patient's cardiac function.


Guidelines for Thrombolytic Therapy for Cerebral Embolism
Cerebral embolism is a particularly dangerous type of ischemic cerebrovascular disease. Patients present with a very abrupt onset, typically with a history of atrial fibrillation. Acute onset rapidly leads to limb paralysis, and may also cause disturbances in consciousness and seizures, among other clinical manifestations. Current guidelines for thrombolytic treatment of cerebral embolism do not address extensive cerebral embolism, as thrombolysis in extensive cerebral embolism carries a certain risk of bleeding and is not generally advocated in clinical practice. Mainly, arterial thrombectomy treatment can be administered within an eight-hour window, which can provide significant therapeutic effects for some patients. Additionally, if the cerebral embolism is considered small and the patient's consciousness is relatively intact, intravenous thrombolytic treatment can be given. The time window for intravenous thrombolysis is generally within four and a half hours, so it is crucial to get to a hospital as quickly as possible in the event of a suspected cerebral embolism.


What should not be eaten in case of cerebral embolism?
Cerebral embolism is a type of cerebral infarction. It is a condition caused by the dislodgment of emboli, leading to the interruption of blood flow in the brain and resulting in the necrosis of brain tissue and cerebral infarction. There are no special dietary requirements for this condition, but it is generally advisable to follow a low-salt, low-fat diet, as high levels of salt or fats can be risk factors for cerebral infarction. Additionally, cerebral embolism can also be caused by atrial fibrillation. Patients with atrial fibrillation must monitor their coagulation function carefully and pay attention to cardiac issues. Regarding the diet, it should be low in salt and fat, and if the patient does not have diabetes, there is no need to pay special attention to blood sugar levels. However, if diabetes is present, diabetic dietary guidelines must be followed.


Is cerebral embolism the same as cerebral infarction?
Brain embolism is a form of cerebral infarction, so essentially, it is also a type of cerebral infarction. Cerebral infarction encompasses a wider range, including cerebral thrombosis, lacunar infarction, watershed infarction, and others. Brain embolism primarily refers to abnormal substances entering the bloodstream, which then enter the arteries of the brain, causing obstruction in these arteries and leading to ischemia and hypoxia of the brain tissue, thus presenting clinical symptoms of cerebral infarction. The onset of the condition in patients is quite severe, rapidly leading to paralysis of limbs and disorders of speech function. In cases of extensive brain embolism, patients may even experience coma and death as serious complications. Most patients with brain embolism have a history of atrial fibrillation. Atrial fibrillation can lead to the formation of mural thrombi, and when these thrombi dislodge, they can cause brain embolism.


Can people with cerebral embolism eat mutton?
Patients with cerebral embolism can eat lamb, but should do so in moderation and not excessively. This is because a common cause of cerebral embolism is the formation of atherosclerotic plaques in the neck arteries, particularly soft plaques. When these soft plaques detach, they form an embolus that, carried by the bloodstream, can block cerebral vessels and cause a cerebral embolism. Thus, many of these patients often have hyperlipidemia, with a basis of arteriosclerosis and arterial plaques. Therefore, their diet should be low in salt and low in fat, and overall light. Foods that are overly greasy or high in fat should be avoided as much as possible, such as animal organs and fatty meats which are high in fat. Lamb can be eaten in proper amounts. Other dietary considerations include avoiding overly salty foods, as excessive salt intake can lead to increased blood pressure, further aggravating arteriosclerosis and arterial plaques, and leading to the onset of cerebral embolism.


symptoms of cerebral embolism
Cerebral embolism generally has a rapid onset and develops quickly, often occurring during physical activity. Within a short period of time, the condition can peak, and patients may experience sudden coma or complete paralysis of one side of the body, as well as aphasia, dementia, and cognitive dysfunction. Overall, the progression of the disease is very fast and can reach a peak in a short time. These patients often have underlying diseases, such as atrial fibrillation, which is a type of arrhythmia. In patients with atrial fibrillation, mural thrombi can form on the inner walls of the heart. These thrombi can detach and, carried by the bloodstream, block cerebral vessels, leading to cerebral embolism. Additionally, some patients have a foundation of arteriosclerosis, particularly in the carotid arteries, which can form plaques, especially soft plaques. When these plaques detach, they can form emboli that block cerebral vessels, causing cerebral embolism.


What to do about cerebral embolism?
The onset of cerebral embolism is very sudden, and most cases of cerebral embolism are caused by heart disease. For instance, atrial fibrillation or myocardial infarction can lead to cerebral embolism, which requires immediate medical attention. If it is within the time window for arterial thrombectomy, it is best to proceed with the arterial thrombectomy treatment, and this window typically ranges from six to eight hours. If the time window is missed, the patient should primarily be kept on bed rest and given medications to protect and nourish brain cells. If intracranial pressure is high, medications to reduce dehydration and lower cranial pressure should be administered. After the acute phase, anticoagulation treatment should also be provided to prevent future occurrences of cerebral embolism. Additionally, care should be taken to prevent complications such as pulmonary infections, urinary system infections, and bedsores.
