General anesthesia during endovascular therapy for acute ischemic stroke: benefits beyond better reperfusion?

The better outcome after EVT in the GA arm was mainly a direct effect-that is, an effect that was not explained by better reperfusion. We also found a better outcome in the GA arm when reperfusion was not achieved. Whether this is an effect of the stable condition and blood pressure under GA or a neuroprotective effect will need to be investigated in future research.
