本题采用两组对照方法观察了静注尿激酶治疗颈内动脉系统进展性血栓性卒中的效果。结果表明：中等剂量尿激酶可使患侧血管血流速度增高，阻止症状的恶化，并使受损功能在短期内得到不同程度的改善，未发现有出血副作用。通过本研究我们认为，这一治疗对进展性血栓性卒中是明显有效的、安全的。 In this study, two groups of control methods were used to observe the effect of intravenous urokinase in the treatment of advanced thrombotic stroke in the internal carotid artery. The results showed that medium dose of urokinase can make the ipsilateral blood vessels increased blood flow velocity, to prevent the deterioration of symptoms, and make the damaged function in varying degrees in the short term to improve, no bleeding side effects were not found. Through this study we believe that this treatment is significantly effective and safe for progressive thrombotic stroke.
