急性脑栓塞具有较高的发病率及致残率,是临床医学的一个难题,临床上80％～90％是由于栓子将脑动脉堵塞,根据堵塞的部位,在临床上出现不同程度的嗜睡、意识障碍、肢体偏瘫。在脑组织缺血坏死之前,将血栓溶解,改善脑部血液循环,促使血液稀释,血管扩张,抗凝等,使堵塞的血管再通,及时恢复供血,挽救缺血的脑组织恢复功能,早期给予溶栓治疗,可缩小梗死面积,改善功能,降低致残率及死亡率。 在明确诊断后,溶栓治疗应尽早进行,溶栓主要影响是再通时间,大多数溶栓的最佳时间为脑栓塞后的3～6小时,因为在脑组织出现坏死前 Acute cerebral embolism has a high morbidity and disability rate, is a difficult problem in clinical medicine, 80% to 90% of clinically due to emboli occlusion of the cerebral artery, according to the site of the blockage, the clinical manifestations of varying degrees of drowsiness , Disturbance of consciousness, limb hemiplegia. Before cerebral ischemia and necrosis, thrombolytic, improve blood circulation in the brain, promote hemodilution, vasodilatation, anticoagulant, etc., so that blocked blood vessels recanalization, timely recovery of blood supply, to save the recovery of ischemic brain tissue, early Give thrombolytic therapy, can reduce infarct size, improve function, reduce morbidity and mortality. After a definite diagnosis, thrombolytic therapy should be carried out as soon as possible, the main impact of thrombolysis is to re-pass the time, the best time for most thrombolytic embolization after 3 to 6 hours, because the brain tissue before necrosis
