Patients with left radiocoronal cerebral infarction have mild clinical symptoms and signs, most of them have no cerebral edema and increased intracranial pressure, no consciousness disorder, and most of them show signs and symptoms of focal neurological deficits, for example, the patients can have hemiparesis, monoparesis, and sensory deficits of the right limbs, as well as hemianopsia and quadrant blindness, and speech dysfunction as well. Treatment is mainly to give anti-platelet aggregation, improve blood circulation and neuroprotection. Commonly used medications to improve blood circulation are mainly Shuxianin, Vibramycin and Chuanxiongxiongzine. Antiplatelet aggregation drugs are mainly aspirin, or clopidogrel if aspirin is not tolerated. Neuroprotective drugs include olaxetan, piracetam, ceruloplasmin hydrolyzate, cytarabine, and edaravone. Butylphthalide is also applied to improve the signs and symptoms of neurological deficits. If the patient’s somatic symptoms and signs are obvious, give rehabilitation treatment as early as possible, including limb function rehabilitation training and speech function rehabilitation training, the clinical treatment effect is better for patients with left radiocoronal cerebral infarction, and most of the patients may not have sequelae.
