Abstract:Acute ischemic stroke (AIS) is characterized by “high incidence rate, high disability rate and high mortality”. In recent years, with the wide application of mechanical thrombectomy, the prognosis of AIS patients has been effectively improved, but there is still a certain proportion of patients with poor prognosis and low overall benefit, and the factors affecting the prognosis of mechanical thrombectomy in different regions and different research reports are different. It is of great significance to analyze the factors influencing the prognosis of thrombectomy for the formulation of clinical treatment plan and rational decision-making. This article reviews the factors affecting the prognosis of mechanical embolectomy, which has been reported in many studies.
