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.
