Left middle cerebral artery occlusion refers to hyperlipidemia that causes the blood to become sticky and form emboli. When the emboli circulate to the narrowed position of the middle cerebral artery, they block the middle cerebral artery, resulting in interruption of blood flow in the middle cerebral artery, which causes symptoms such as hemiplegia of the limbs, salivation at the corners of the mouth, distorted eyes and mouth, and even coma. In the case of acute middle cerebral artery occlusion, emergency thrombolysis or arterial thrombectomy is required. Middle cerebral artery occlusion can be treated with arteriography and stent implantation to open the middle cerebral artery. Patients with middle cerebral artery occlusion need to take anticoagulant, lipid regulating, and circulation improving medications to prevent recurrent occlusion. It is also important for patients with middle cerebral artery occlusion to recover at a later stage. They should have a low-salt, low-fat diet, eat more fresh vegetables and fruits, choose coarse grains or whole grains as much as possible as their main food, exercise in moderation and take care of their rest.
