Abstract:Objectives To investigate the clinical features and prognosis of anterior choroidal artery infarction. Methods Seventy-seven patients with isolated AChA infarctions were selected. The National Institute of Health Stroke Scale (NIHSS) scores in one week were evaluated. Patients were divided into two groups: the progress group (35 cases) and the non-progress group (42 cases) according to the NHISS scores. Risk factors, clinical manifestations, vascular imaging characteristics and prognosis of the two groups were analyzed. Results Hypertension is the most common risk factor of AchA infarction (P < 0.05). The progress group was more often associated with dyslipidemia, diabetes, hemiparesis and internal carotid artery or middle cerebral artery atheroma (P < 0.05). There was no statistically significant difference in the prognosis between the progress group and the non-progress group (P > 0.05). Conclusions Hemiparesis is the most common symptom of AchA infarction. Hypertension is the most common risk factor. There was no difference in prognosis between the two groups.
