摘要：
We studied 383 consecutive patients with stroke and ischemic lesions on CT scan for the presence of symptomatic cerebral infarction (SCI) and asymptomatic cerebral infarction (ACI). We evaluated risk factors as well as volume, site and number of the lesions. ACIs occurred in 34% of the cases (130/383); 88% of ACIs were lacunes and internal borderzone infarctions, with a volume of less than 2 ml. Larger infarctions were asymptomatic in 27 patients (20.8%); 114(68.7%) out of 166 patients with two or more SCIs (68.7%) had one or more ACIs. Infarctions in the lateral middle cerebral artery (MCA) territory were SCIs, in the medial MCA territory ACIs. Independent risk factors for ACI were age above 70 years and smoking; cardioembolism prevailed in SCI, small vessel disease in ACI; high levels of disability prevailed in SCIs.
