Hypotensive cerebral infarction, also clinically known as hypoperfusion cerebral infarction, for this infarction on CT or nuclear magnetic manifestation, can become bead-like lesions. The patient’s clinical symptoms can involve the anterior and posterior circulatory system, usually the brain tissue between the two blood-supplying arteries is damaged, and in the hypoperfusion infarction in the middle of the brain and anterior cerebrum, the patient can have mild paralysis of limbs, mild stupidity, and also accompanied by dizziness, and so on. If it is the watershed area of blood supply between the middle and the back of the brain, it can be manifested as vertigo and visual field defects, visual blindness, walking skewed, and can be accompanied by limb soreness and weakness. For hypotensive cerebral infarction caused by low perfusion, patients are advised to supplement blood volume, and if necessary, they should be given volume-expanding treatment, and at the same time, they should be treated with anti-platelet aggregation, blood circulation and blood stasis activating drugs.
