Acute ischemic stroke (AIS) is a clinical syndrome caused by blood supply disorder of brain tissue, which has the characteristics of high incidence rate and high disability rate, and seriously affects the quality of life of patients. Intravenous thrombolysis is currently an important treatment for AIS, with alteplase being the only thrombolytic drug recommended by all guidelines. However, some patients did not experience improvement or even experienced deterioration in their neurological function after undergoing thrombolysis. Therefore, this article reviews the current status of treatment research on promoting neurological function in patients with AIS after intravenous thrombolysis, in order to explore the importance of combined treatment strategies on further promoting neurological function improvement.
