Abstract: Objective To study the effects of thrombolysis on short- and long-term outcome in acute cerebral infarction patients. Methods The patients accepted thrombolysis and remained severe neurologic deficits were as observation group (n=29), and the patients without thrombolysis matching the onset time and severity of disease were as control group (n=94). They were assessed with National Institute of Health Stroke Scale (NIHSS), Manual Muscle Test (MMT), Brunnstrom Grade, modified Barthel Index (MBI) when they admitted and discharged, and with modified Rankin Scale (mRS) 6 months later. Results The scores of MMT, MBI and Brunnstrom grade improved in both groups when discharged (P<0.05), except the NIHSS in the control group, and the scores of NIHSS and MBI improved more in the observation group than in the control group (P<0.05). The score of mRS was better in the observation group than in the control group 6 months later (P<0.05). Conclusion Thrombolysis can improve the neurologic function and activities of daily living in the acute stage of cerebral infarction, as well as the long-term outcome of activities.
