Does Hyperdense Middle Cerebral Artery Sign Predict the Prognosis of Patients Undergoing Emergency Endovascular Treatment?

HMCAS may not be a predictor of 90-day mRS in LVO-AIS patients undergoing EVT. However HMCAS+ group patients had higher stroke severity before IVT and EVT. In the era of EVT, the factors affecting the prognosis of LVO-AIS may be different from those of the past.
