Most cases of cerebral embolism in patients are caused by heart diseases, especially in patients with atrial fibrillation. Thrombi form in the atrium, detach, and travel to the cerebral arteries, causing a cerebral embolism. If the area affected by the cerebral embolism is small and the symptoms are mild, surgical treatment may not be necessary. Patients should rest, engage in rehabilitation exercises, and be treated with medications that invigorate the blood, remove blood stasis, protect brain cells, and use anticoagulants. However, if the embolism affects a large area, such as the middle cerebral artery, interventional surgical thrombectomy can be performed according to current medical advancements, which may be effective for some patients but also carries risks of bleeding and potential surgical failure. (Please use medications under the guidance of a doctor and do not self-medicate.)
