Early vs. delayed neurological improvements in acute ischemic stroke patients following endovascular treatment

Objectives

Early neurological improvement (ENI) at 24 h after endovascular treatment (EVT) is a surrogate marker for predicting functional improvement of acute ischemic stroke (AIS) patients; however, using delayed neurological improvement (DNI) at seven days post-EVT remains understudied. We investigated differences between ENI and DNI in predicting functional outcome of AIS patients undergoing EVT.
